Medical discrimination? Also fear of retaliation?

I have recently been put on a new medication for depression and it has left me unable to drive for about four weeks so my husband drives me to work. My employer has known of my medical issues for the 4 years that I have been there I was on disability before I started working there. Now just the past week she's been constantly saying we're losing money because my inability to drive at the moment and not being able to afford tires because my husband is out of work from a motorcycle accident with a broken femur and now has a rod in his thigh, and it seems everything I do to help I feel like its wrong or constantly micromanaged by my medical problems. I love my job. I feel like they are trying to do everything in their power to make me quit and I have talked to her about it and its just brushed off or its still my fault in some way. I dont know what else to do besides quit but we can not afford for me to do so with having my step children. Small family business has open signs everywhere. I've looked up the laws here and they are pretty much for the employer and not the employee and retaliation is their strongest suit with all the ex employees I've seen over the years.
