Is it illegal?

I recently was put in a very upsetting situation by employer not only for my job but my personal life as well, I just need to know if the actions being made legal and if i have any case based on slander, hostile work enviroment, gender, and unethical practices. So I am 24 yrs of age and in 2015 I had landed myself into trouble and was incarcerated for a short time upon my release i had moved to another town and started down a new path. while being incarcerated a friend of mine, who is a male, his fiance started writing me letters and befriended me the week i was released my birthday came around and as his fiance and now what i thought as a new friend came as promised in her letters ( the reason im telling you all of this will make sense as you read on). And 2016 turning onto 2017 I lost my job in the Newtown I have moved to so my friend that I spoke of before and his fiance worked at a restaurant in my hometown she being the manager had me driving back and forth an hour and a half Drive to work because I needed money and she needed an employee now while this is going on I got to work and she pulled me to the side sit down at a booth and as to her like a full-time position and told me if I move to towns you help me with a vehicle and she will help me with a place to stay and I told her right then that I did not want to accept the job unless there was room for advancement when she asked me what I meant I meant like could I move from a dishwasher to a waitress she said of course. And then movement moment things back to holder and started staying with my grandparents and do time she had help me to locate a cheap car right from the beginning it seemed like there was no room for advancement that definitely would not want me out front and then the girls would even like for me to back them up and my friend I was telling you about was main cook in the kitchen for the evenings and what I would try to explain things to him he told me I was nuts that they wouldn't do that I hardly ever going out front towards the end of my dish washing because the girls were standoffish and didn't want me up there and also because I never really got tipped out so I didn't understand why would do more than my job duties once I finally gave up on trying to help them I had expressed some things to you the over at the time and she told me to grow up which really made no sense as a response now in the beginning of 2018 or maybe the end of 2017 my friend and manager and my friend's fiance I bought the business and became the owner my friend had recently found out that and his diabetes was not in the best of shape keep having dizzy spells and things so then she told him she didn't really want him at work in case he was depressed out while he's still receiving his pay the entire time and I'm doing both of our jobs so I walked out on a Friday because all I walked out and left like I did I didn't think I had any grounds to stand on for the fact that that Friday my check was only a measly $92 and I know it was short but I had no proof because she had been doing my time sheets for me as later she had message me once I did it walk out and try to send me a picture of proof of my hours I told her and him both that that was not proof enough for my hours that is unless they wanted to go through and sit down and watch it be video surveillance that have been recorded on to the DVR to add up my hours of the night and home discussed it any further. So again in 2018 she offered me my job back I told her I could not take it back unless you was going to pay me more and unless I got more floor time so starting back they're at the customers I thought were actually happy to see me back there gave me a boost of confidence I did better on the floor and in tips the only downfall was one of my co-workers who would not back me up like they do for the rest of the girls when they're on the floor all right like when I was supposed to work with another co-worker and they would not answer my questions they just kept treating me like I was stupid and I had to report this to my boss on numerous occasions one girl even did it walk out because she was mad about me having for time which I'm still confused about and just within the past month my friend/boss decided to leave her fiance and I was uncertain of what was going on tonight that it happened because her family and everybody was there running around changing a lot spending three years with this woman I was confused about what was going on I know everybody at work have been treating me funny that day but wasn't sure why well towards the end of the night and finally asked her what was going on and she said we'll talk about it when you get done when I finished what I was so then when you went to take me trash out together I finally asked her what was going on she said here is $200 take it back to her fiance help him to pack his things that she couldn't be with him anymore so I was automatically thrown into the nipple upon her leaving her home she left on their bullets and everything else and the way I was taking it was that he may have been suicidal the next day he was not very happy or cooperative with the fact that she was in her relationship with him up 7 years over a text message so the next day he has this gone and he has underneath his pillow and I was worried and she had thrown me in the middle of it to help him back so I was there trying to get into bag and I need to be to work soon and then I realize I had my sandals on I had text her and texted her I had asked her earlier in the day what time I needed to be in to work because she only would have me come in if they were busy at that time once I start picking up otherwise there's no need for me to be there on the clock if they didn't need my extra hands it was a daily routine so after this she finally started to text me back and then my message I texted her and she said no I was a good worker that's why I'm tired back and that she was really my friend and lied to me I still have the messages on my phone thinking back to when I did my walk out I got concerned with this entire situation and I downloaded an app onto my phone that recorded any phone calls between my boss's number and the businesses number and my phone my bosses fiance's mother also works here they worked there before she even ever worked there like 2 or 3 owners Pryor his mother was telling him that her mom which is also up there with us was standing in front of everybody stating how Jimmy has never really liked me this entire 3 years boy secretly hated me and that she just wanted to keep tabs on me that's why she kept me close and that she came home and caught me and her fiance doing something together which is false and slander even though in this I still took myself in to go to work and I try to go into the back door because I wanted to tell her mother what I was late for and explain to her the situation with her fiance and the gun so I called the restaurant and the girl co-worker the answer the phone left me standing at the back door and then she turned around to tell everybody there that I was told to go around to the front I have the recording and it never once was stated for me to go around to the front door she left me standing there feeling very embarrassed feeling very upset with all the situation and all the stress that was being put on me and my job and my life I just left once I left my friend and boss finally started to text me back when I have been calling and texting her the entire time I was at the back door and she asked why isn't my mother there and then finally told me to go around to the front door I was already gone I'm confused I don't understand the entire town is being told these lies now I don't want to go to the grocery store don't understand how somebody could do that to somebody she employed me she bought me gifts she's taking me places she's loan me money even helped my family I've seen this girl every day for the past three years of my life and now this is what I get it's all these people in town saying these things and her telling people that she was forced to hire me back by her fiance and all of these other lies I can't show my face in town because all these people believe her because of my past record and the way my past looks compared to hers everybody wants to take her word for it I don't even know why somebody would do this to somebody if they really hated them why would they move them back I work for them have them around them everyday talk to them confide in them I told her more secrets in I have told my sisters for her to turn around and make me out to be somebody I'm not and somebody that I don't want to be and trying to claim me to be exactly what I work so hard to clear my name up and I'm just ashamed and I am distraught what do I do is this legal is this professional at all?
