A little advise please?

Many of you guys know the crud that I am going through at work.  I got chewed out, again, Friday afternoon.  I was pretty upset and when I was going to bed last night, I remembered that I didn't do 2 very important things for Monday morning.  So I know that when I get into work I will get in trouble.  I ended up staying awake until 3am, freaking out.  I hate feeling this way and I hate being scared to go into work.  

My question is- should I leave my job?

I was going to call the temp agency I worked through first thing Monday morning and see if they have any spots for me.  My money will come in sometime in the next month or so, but I am not sure if I can wait until then.  Work is effecting my sleep, my hunger, I sometimes have heart palpitations at my desk and I dread everytime I see my boss come down the hall.  I'm not sure I can hold out until the probate closes, even if it's a few months (we're still looking at the end of October or early November for the estate to be finalized).  I've tried talking to my boss and I do everything she asks of me, even when she changes her mind on how I'm to do my job and gets mad at me that I didn't do what she said 5 seconds ago.  In the 4 years that I have worked at my job, I'm the 4th HR person.  The last guy lasted 3 months.  Ive been doing this 5 months. So I know it's not me 100%.  When I first took the HR job, I was very upfront with my skills and what I could bring to the company.  In August she started to single me out for her anger.  I don't think a day has gone by in the past 2 months when I didn't get chewed out for something.  Right now, I am being babysat and I have to run everything through her.  If she's too busy to see me, I have to wait.  Then she gets mad that I didn't do anything.  I honestly think that she's trying to make it hard on me that I quit.  She doesn't want to fire me because then they would have to pay unemployement.  I looked into whether this would be concitered a hostile work enviroment, but it does not.  The lawyer I spoke to said that it's not illegal to be a jerk.  I've talked to a friend and one of my Mom's friends and I was wondering if there is any advice you guys can give me.
Thanks
