My 2nd year is my worst.

It's my 2nd year teaching at a private school and I think it's the worst compared to my first. It's about me. How I handle my stress, coping mechanisms, juggling my schedules (which Im6really having a hard time at. time management is really hard for me) and etc. Parents complaining about late announcements, coaching several pupils for contests, tutoring a pupil outside of school hours, taking up my master's degree (which is a little bit hard that what I expected.) expectations of the people, etc.... As a result, forgotten tasks, overeating/ not eating at all, overthinking, headache, crying at night wondering why did I even take this path? Should I quit and follow my dream? (which I don't know which career but I wish I don't have to deal with parents and kids anymore, I wish to have flexible time, that I would be able to relax by myself)
