You can be successful if you find the right job. I quit so many jobs and got fired a few times. Just hated the job itself and/or the lame people that worked there.
Finally found one about 4 years ago working for a non-profit. We are allowed to let our feelings and thoughts be known-vent. In this way I do not have to stuff my emotions until I feel like crap, and also they know about the BP and help me when I get overwhelmed. I am accepted.
So don't give up, it can happen.
