When you communicate with the members of this forum (or maybe other people online,) that is a form of socializing and dealing with people as well - I believe you have the courage and capability to deal with people by yourself. You've even found people who have things in common with you (like enjoying anime )

Have you ever tried calling a hotline (some sites even have chat options) The forum has listed quite a few.

Lifeline
Suicide.org: Suicide Prevention, Suicide Awareness, Suicide Support - Suicide.org! Suicide.org! Suicide.org!
Kristin Brooks Hope Center - Hopeline
Suicide Forum - A support forum for people in crisis

These sites aren't only for people who are suicidal, but I feel these professionals are much more qualified to help you then I.
