Feeling sad, I think maybe the byzantine is right. I know that you feel so strongly for this friend and that fo you, the sun rises and sets in him, yet I am also starting to get the feeling tht you are losing yourself in his problem. I recommend strongly that you check out a book on codependancy or check and see what there is on the webb about it. There is nothing wrong with your love and loyalty, hon, but you are so afraid of losing him that you risk orienting your life around him as a sick person and his problems and that isn't good for either one of you. you aren't repsonsible for his feeling, and you can't do much more than let him know that you'll be there when he needs you. You can't do his part in the realionship for him.
He must be wonderfull for you to care so much! Huggggs in a big way.
