I’m sorry that things have been so difficult for you lately. Fifteen is a difficult age and friendships can come and go quickly. It’s unfortunate that you have such a small peer group to pick from, being in private school. It sounds like you already realize that punching the kids who were teasing you was not the best way of handling the situation, although I do believe that it is important to stick up for yourself.
The fact that you feel bullied, your grades are dropping and you aren’t eating regularly are all signs that you need some help. You need to reach out to the school counselor or ask your parents to find you a therapist outside of the school. You also need to let the school administrators know that you are being bullied, if you haven’t already.
Don’t give up on trying to make new friends or giving your old ones another chance. Like I said, things between friends can change rapidly and frequently at your age so the tide might turn back in your favor. It is also important to find things that you enjoy doing and activities that you feel highlight your skills so that you can begin rebuilding your self-esteem. Remember that this time in your life is only a chapter, and you have an entire book to write.
All the best,
Dr. Holly Counts
