Hey guys I don’t know if this is the right place to post but I’m super afraid of losing my job.

I work per diem for a company where I pick up which hours I want to work, which works out great for the most part because if I’m feeling extra bad one week I don’t need to work if I don’t choose to. 

But there are some times where I choose my schedule a month in advance and then when the time comes to go to work.. I just can’t. I’ve missed a lot of work and my boss basically told me if I miss any more I’m done completely. I feel like BPD has taken everything from me and I don’t want to lose this job as well. I love my job. 

I’m doing really bad right now and currently going through med changes that are making me feel worse and for some reason I had picked up 3 shifts this week and I’m dreading them but I’m gonna try to power through. 

What steps do I take to protect myself in case of missing work? Do I just email HR saying hey I have a disability that may make me miss work once in a while? Do I have to fill out ADA paperwork? Do I need a note from my doctor with what disability I have? I don’t even know where to start and I’m really nervous and stressed about this. Any input is appreciated.
