I'm thinking of quitting my job as a teacher
Do you have any idea what you would do instead of being a teacher?
I want to do something more interesting
If you don't enjoy being a teacher anymore then you should do something else. It isn't good to stay in a situation that isn't making you happy.
True. And get this. I don't know what to think, a student crushes me pretty hard though.
It is good to remove yourself if you are unhappy with your job. If you feel like you are in a situation to be inappropriate with children you should seek help.
