My group of friends on xbox live are always there for me, but now theres a new 5th person in our little group. All he ever does is put people down and make fun of people. Today i kicked him from the party because he told me to go kill myself. After this he messages one of my friends and tells him that how he acts helps him with his depression and other problems and that i needed to grow a pair and deal with it. Then all of my friends join his party and they invite me. He says, "oh, there's the little asshole who doesn't care about anyone." As soon as I heard that I simply left the party and turned off my xbox. Now, I have some pretty bad anger issues so i sat on my bed for a while trying not to punch a hole through my wall. I've gotten it under control a lot more than a couple years ago. One person grabbed my arm once when i was angry and i proceeded to grab the sleeve of his hoodie and rip it off. I also used to get into fights every other day pretty much at my school, to the point where my principle and I were on a first-name basis. Can someone tell me what I should do?
