When someone spills his guts out, others should listen and try to be supportive.

Asperger syndrome is my inheritance, three generation now. Also my father is bipolar (real ugly). As for feeling bad or being unhappy, I just say "so what, fuck it" and try to find beauty and love in anything around me, or at least just live for the experience. The bright side is that life doesn't last long so enjoy the good times and remember the bad times will be over soon.
