A snitch away from suicide?

Over the last little while I have suffered from depression. I can't seem t fit in with my friends, as in I can't get involved with conversations and get attention from them. I tried being a quiet guy that didn't work so I tried being a out going attitude guy and that did not work. I talked to a suicide hotline and they said that its just a personality thing and that I should not worry about it. But for some reason I still feel depressed. They told me that if I committed suicide that everyone would miss me, well my guess is that after a week my friends would forget about it. What should I do?
