Razor, the thing about suicide is that it always seems the most logical thing to do when you confine your actions to only existing in your current situation and current environment. The solution? Change your current situation and change your environment! The world is a mammoth place, and there will always be somewhere for you to start out new. Maybe the relationships you've gotten into and out of are painful, but try going somewhere else and volunteering for something. You'll have a reason to be there (want to help out, need community service hours, whatever) and it's a great excuse for hanging out with new people.
Back when I contemplated suicide, I could only comprehend that horrible notion of having to live this way of life, or else no life at all.
But, thanks oddly enough in great part to Youtube, I realized just how much depth there is to this world. On one hand, it seems that everyone around me is happy and satisfied, but then I read about all the pain and suffering that billions of people in the world go through everyday.
One unorthodox therapeutic method that worked for me was reading a textbook on Abnormal Psychology. It really helps to put things into perspective, and you may feel consoled by the mere standardization of what each individual perceives to be his or her own unique problem that no one in the world could possible share.
Reading the diagnostic factors of dysthymic disorder (a depressive disorder) made me go, "Holy honeysuckle! This is EXACTLY what I'm going through!", and it somewhat comforted me that about 6.5% of people have to deal with this same exact thing.
