My friend (male) is having some problems .. He is quite a cynical person, who doesn't trust anyone but then if he finds a friend, he gets attached to her/him alot .. If his friend gets busy somewhere, he feels like she/he left him .. He is not a social person .. Many of his close friends are on internet!

Yesterday, he was asking me that how can we forget a person we like alot!? Does making oneself busy help every time? He has also a problem of self-injury .. When he gets depressed, he tends to injure himself .. Now this problem is projected towards hurting & injuring others especially those who have hurt him in the past!

I m myself a student of Psychology Major .. I have worked with him alot.. as the guy is facing alot of problems in his life ..

Kindly, give me some good suggestions which can help him !!
