So you only told them about your condition after you felt like they were about to fire you? A serious condition you only shared after reading that the US ADA might protect you? Something feels off about this.

A part of your performance might have needed the communication because as you’ve said everyone works remotely for the said company. Lack of communication can disrupt the harmony of the team that makes the company work.

I do feel for you because mental health issue isn’t something anyone should take lightly.

If you were getting fired because of your performance or lack of communication isn’t helping the company anymore without them knowing you were going through this mental health issue, is it really grounds for discrimination? From what I understand they were letting you go because of the communication not because of your mental health.
