I need some friend advice, someone please help, this has really taken over my life?

Tell him everything you just said right now. Bring back the memories to him and make him realise that he needs you more than his xbox. Tell him you can help him and that you dont care bout his acne or anything. Listen, write him and email or a letter and post it at his house. Or go into the house and even if he doesnt open the door, yell from outside. Make him realise you DO CARE !
