I got busy, I got a job, and then I cried

I think I have Ergophobia.

I've been stage managing a play, and running a box office for another show.  I've been happy, but not getting paid.

I got a job today.  I'm so terrified.  I start on Tuesday.

My last job screwed me up emotionally.  I feel emotionally abused.  I'm so scared that I'll get fired, and I know that comes from my last job.  I was scared I was going to get fired everyday.  My anxiety level is out of control right now. 

I should be happy, but I can't stop worrying and crying.
