Help, severe seperation issues!?

I have a friend who isn't even like my best friend or anything, but i feel extremely attached to him. I depend on him in cheer me up when i'm down and to control me when i go into one of my rages. I have asperger's syndrome and i don't really get people, so i'm really confused by this. Whenever he is mad at me or i can't talk to him, i get really depressed and i have uncontrollable rages. I have no idea why i am like this! I need help before i injure myself or someone else.
