I am really bummed out right now. Not sure what to say?

1) My friend's younger brother committed suicide. Its disheartening because he was a great guy and my friend and his family are devastated. He was good strong level headed guy so no one saw it coming. He left a note describing some issues. The short of it is that he was being harassed by these sick psychos. A lot of them were his friends at one point. They had a falling out, and everyone sided with another guy in their friend group. It looks like they made up with him, and then back-stabbed him. Created a very unhealthy environment for him and subtly pushed him towards suicide.
2) On a different note, relationships with my girlfriend is rocky.
