Help!

I'm a 1st year teacher at a private school and I thought I would come back another year but now I'm not sure. The parents are board line harassing me, it got so bad we had to put security measures into place. Also, we haven't had subs so l've been pulled into cover for other classes and am not getting planning periods/lunch. I'm the only teacher in my grade so I get zero help with lesson planning and rely heavily on my planning periods. I tried telling my principal no when he asked today and he got mad at me.

I think I want to leave but idk what job to do since l have horrible wrist pain and can't type 8 hours a day.

Please, help!
