And welcome to the forum. A doctor may send you to a counselor, which I feel you need. They may also give you medication, which you may need.
I think the biggest thing you need to learn is we don't always get what we want in life and there are going to be times that we are told no. You have to learn to accept that and deal with that. It will make your life much easier if you do.
Seeing a counselor would be good for you as you will learn better ways to cope than you are now. Harming yourself isn't the answer. But you will find what is the right answer for you. Coming here is good. We can give you suggestions as to what has worked for us. Please keep posting.
Take care, and I hope that you feel better.
