sorry to hear this mate
one of my mates did this last year. we had grown up together and i was with him the day before he done it and he was fine. i got a fone call at work to tell me what had happend.
its had to take at the time and is the most dificult thing ive ever had to go threw but time is a healer.
i think about it everyday but uve just got to get on with it.
i knew people were there for me so just do the same as it does help
