HELP! WHAT SHOULD I DO?

Good idea on leaving. I think friendowl had a good point, that would have been a good step, and if things didn't improve then the 2weeks notice would have been next. But your mind's set.

Really, you're young only once. Take advantage of it and go to school. It doesn't take that long to complete and you'd rather not regret it down the line. As for the job, trust me, I've learned that if a job isn't treating you right, it's not worth it. I've tried to fix things on numerous occasions and come to the conclusion that you should give it one good effort, and if that doesn't work, it isn't ever going to. So in those situations, I put in my 2 weeks and bounce like a hot check. I do say my goodbyes respectfully to employees who deserve it. But I make it clear to those who need to know exactly why I'm leaving.

I think you're making a good choice. Good luck.
