I did disclosure my condition 4 days before the HR meeting where they fired me. Sent all my docs diagnosis and letter. I only acted based con my intuition what that meeting was about. Actually the meeting wasn't with HR but my manager, just in a weird hour (1am). I figured out HR had another call scheduled same time with my manager (which I was not invited) but public in the company calendar. I did it because I knew that I had to do it BEFORE the call. Even I had a call with HR and they supported me. They had enough time.
