Try appealing your case, that is my vote. You’ve been through a lot!!
My daughter had to ask for accommodation in college because her father died.
My husband died in 2012, and I truly believe that bipolar means you suffer grief harder because of it. I got worse after he died; I finally got diagnosed three years after he died.
It hasn’t been long enough for you to recover fully from that. I know how hard it is; I was let go after my husband died, four years after. I wasn’t ready, but I got through it.
You will too.
