Will I get approved for unemployment benefits if my former employer states that I "voluntarily quit"

I have been recently going through a lot of personal problems which was effecting my state of mind while being at work. I kept calling out because I have extreme anxiety and depression. After about one month of calling out about once or twice a week, I called out 2 days in a row and the next day (which was my day off) I received priority mail from my employer stating I was terminated. They asked me to sign a form stating I voluntarily quit and a note on the side stating "job abandonment". One week prior, I informed my supervisor of my anxiety and depression and gave very little information on why I was still having these feelings even while on medication. He suggested I take a few weeks on a leave of absence to get myself together. I informed him my psychiatrist just left my normal doctors office and I was going to make an appointment with a new doctor to see if I could take this leave of absence. I had not yet had my appointment with my psychiatrist and now my former employer is trying to get me denied for my unemployment. I have medical proof that I have anxiety and depression and proof of the events that were taking place to make my depression and anxiety so much worse. Unemployment stated I was "monetarily eligible" but my employer is denying my claim. Is there any way I can get approved for my unemployment?

All areas I'm familiar with have an appeal process and they notify you. Call your unemployment office to make sure you clearly understand the appeals process so you don't make another move that will deny your claim.
