So I have just started playing basketball again at my school after not playing for a year due to an injury. When I use to play, I would get very frustrated with myself but was over it in a few hours. Now, its like every time I do something wrong (even if its not my fault) I get so angry that I want to just break something. Its like total rage from then on out and I have a difficult time calming myself down. It takes all my will power not to break anything. I tried breathing exercises but they don't work. I think I might have anger management issues but I feel like I can't talk to anyone about it and if I did I would just get more angry. Any advice?
