I don't want to listen to my friend's suicidal and depressing problems
Is there a reason to not want to listen?
I just hate hearing about all that
Their problems might make you uncomfortable. But as their friend you should be there for them through the bad times, not just the good.
Seriously? I'm feeling good now, I want to leave and not to listen to this shit.
It might be helpful to talk to them and try to help they find a professional. You should not have to deal with the emotional burden that they are going through.
