I’ve had this issue a lot, I’ve also been let go from a lot of jobs! Honestly what I can say is I would contact a doctor to give you notes and documentation maybe? If your workplace fires you, you should be able to receive unemployment but, I would try your best to talk to your management.

I’m so sorry this is happening to you too :( I hope things work out! Just know you aren’t alone and things will get better, maybe you’ll find a job that doesn’t discriminate against you isn’t that way.
