What should i do?Is there anything i can do?

i have this friend and he knows i cut myself and he tries to hurt himself too but he tells me his skin doesnt cut unless he uses something very sharp.well the first time he told me he cut was the first time i told him i started again and when he showed me his first cut it was so big and deep i looked at him in disbelief i had always thought his life was perfect...i guess i was wrong.right after he showed me i asked him "why"just that simple little word and he didnt answer me and asked him if he wanted to talk about it and he said he didnt think so.i dont know what happend to him,he's always depressed and his head hangs down and sometimes he scares me.he wont tell me anything he's hidng from me...i want to talk to him but this time not about my problems i want to know whats wrong with him but i know he's scared to start talking....what should i do?he has always been there for me,i want to be there for him but he wont let me.

youll just have to be patient ive had this truble with my bessie mate , but i didnt tell her soo mabe that dont count . but if ur patient and show him ur a good mate he may just come out with it , but do not nag him to tell you. just be there for him or give him some numbers to ring. itll be hard to tell you whys hes doing it , i havent really told ny1 my reasons. just keep an eye out and if u think he might try commit suicide go get help for him plz. i hope some of this helped , luv lidxxXxx

thanx i just hope soon enough he'll let me help him...
