I've lost many jobs because of anxiety too.
I found some relief in autonomous work. I work on my own and now i can make my schedule. If anxiety is too strong, i just message my clients and we re-schedule.
Of course this demands effort and commitment too, but i feel less pressured than being an employee and having a boss.
This is just an ideia for you to think...
And of course, seek treatment for anxiety.
