My life is so stressful right now and I feel like I am at my limit.

the main source of my stress is my job, which is very high pressure with a boss that for lack of a better word is mean and unstable.

I work in the corporate world, in human resources, where you'd think people would kind of be nice.

My boss has screamed at me, in front of others multiple times.
She treats me very differently than anyone else on my team in the exact same position - constantly tells me no, that's wrong, don't do that, and eventually, that if she'd done it, it would be better.

i've had multiple panic attacks at work - the first time she yelled at me it was on the phone and i pretty much hung up on her - the last time I just walked back to my desk. i generally excuse myself to the ladies room or go outside for a few minutes till I calm down.

I am very good at my job - she has told me how great everyone thinks I'm doing - but then 20 minutes later it goes back to the negativity.

the worst part is that i'm not even an employee of this company - i'm an hourly consultant - if i don't work, I don't get paid, so no sick days, no paid holidays, but also no overtime.

The company that pays me knows about these issues and is trying to help me find a new position. I look every day for a new job.

My problem is that a) I can't sleep because i am so stressed out - I sleep about 4 hours a night even with my meds so my being overtired affects my emotional state
and b) I'm on the verge of tears from the time I start getting ready in the morning, throughout my entire day. Just sending a note to my company to let them know I got yelled at again sent me into panic.
c) this is affecting the rest of my life - my hsband and I are already on shaky ground - this isn't helping

If i quit I can't get unemployment, and i can't afford to be without that income. This has been going on since mid December now and i feel like I can't take much more.
