I'm sorry to hear about your buddies man, suicide is always a difficult tragedy. To me, it seems more strange/tragic. I'm not sure how to describe it, but I guess I have just always thought more about the family and friends left behind. When someone dies in a car accident, we are sad, sure. But at the same time, understanding that those things happen in life helps us grieve and move forward. It seems like we get through it easier.
Suicide, that's totally different. I have always thought it was much more sad and devastating to family and friends, I guess because you realize that someone you love decided that their life was so awful, they didn't want to live anymore. I couldn't imagine the feeling that the only way out of the situation, the only way to overcome your troubles, is taking your own life. I can't wrap my head around that.
As far as AAS being a factor, I'm with
@Dr JIM in the fact that there was almost certainly preexisting psychological conditions, and while AAS may have not been the trigger, it certainly doesn't help to be taking them in an already unbalanced emotional state. They definitely will put you on an emotional rollercoaster sometimes, especially if used incorrectly, so when you think of being really low, remember, that's YOUR low. Now what if your low was someone else's high? What if the worst you have ever felt, the most depressed feeling you have ever been through, was the closest thing they had to joy in their life?
What would their low be like? We couldn't imagine. So to say AAS "caused" it is probably a stretch, and certainly never likely to be proven (although might take the blame in the media, as it has before) but I think we can all agree, based on our own use, that using AAS is definitely something you have to be mentally prepared and stable for.
