Need advice about my job! Help!

Im going insane. pretty much every one of my jobs has sucked with the exception of one. Im still in school, so Im sure it wont be this way forever...but Im so stressed out its driving me crazy.

So anyway!! My current boss is a real bitch. I bust my ass at work everyday and and she ALWAYS has somethig negative to say. The problem is I seem to have this issue everywhere I work. Now Im starting to think its me...that Im being too sensitive?

I just need advice really bad. Quitting is not an option right now! So any advice would help. Thanks reddit.
