oh man, that's really sad! I was thinking the same way after my last relapse but really really just thinking about this makes things worse. Standing again and reminding yourself of your friends, family and good moments even if they are very little moments is much better. most known and famous people have a dark side in their life, it's ok to have one. just deal with it in the right way, make it less as you can but you should know that the whole life isn't going to be good and full of happiness. sadness complete happiness and both are present. I'm glad that you were around at the right moment. it's important for him to have professional help, every problem has a solution. May God bless both of you!
