Can I file for unemployment if employer was planning to lay me off and lead me to resign instead?

My company was going through a reorganization and my position was on the chopping block to be dissolved. Work was being taken away from me and employees were not speaking to me. It was miserable for 8hrs a day. I felt they were forcing me to quit, so I put in my resignation, which they of course accepted. Then they announced to the entire staff that my position was indeed being dissolved alluding that I would have been let go. Can I still file for unemployment, since the last declaration was them saying that my position was being dissolved in the reorganization process that had been going on for months? The immense stress, isolation and deterioration was unbearable. I work in an at will state. Thanks!
