Anger/headaches/ repressed emotion?

At 17 you should be out having the time of your life. Hanging out with friends, going on dates, stuff like that. Sounds like you had a rough upbringing and there is nothing wrong with being angry about it. You may need to seek out proffessional help, therapy. That is nothing to be ashamed of. Everyone has a hard time sooner or later and I believe that everyone could benefit using a counselor. Find a healthy way to release your anger, excercise, boxing is always good. Excercise in general releases a feel good hormone in your body and help eliviate anger and sadness. Try both of these things an I am sure you will feel some relief. Good luck and God Bless
