Can you help me before I end it?

[whocares]

I didn't get a helpful answer last time so I'm posting it again.
What do you tell some one who has no hope or desires, has difficulties trusting people, and wants to die?
Every site I looked I can't find one reason why I shouldn't commit suicide. It's either for people are depresses for a different reason, or they're religious, or the person didn't know what they were talking about. 3 or 4 years ago I decided that if I didn't get better I'd end it at 18, now I have about 3 years left and that tinny little part of me that wants to hang on for a while longer drove me to do this.
Right now I have little to no drive or ambition and I only do things to just get by, I have no friends, and I don't care if I hurt my family because their death would barely faze me(I know this because when my closest family member died last year I can't say I felt anything)
So all I'm asking for is a good reason, any reason involving god wont help AT ALL and will make him look like a prick, as for hell, I have heard so many versions of that place I don't give a rat's *(s)s if I go there.
