Welcome to the forum, I'm sorry you have to go through this, being diagnosed is already too much to handle, but being at the point of loosing your job is stressing. Having single antidepressant is a bad idea, it's known for inducing mania in bipolar patients when used alone without mood stabiliser. Please see a pdoc, being diagnosed and treated is way more important than career, without a proper treatment anyways you might be up to something that can spiral out of control and make you lose the job. Take care of yourself!
