Suicide:Is it worth it?

It is a question I have never really thought of. Not like how I'm thinking about it now. I can't believe I am going to put this online but now I'm too desprate to care. My life had just been picked up again. It had shattered when me and my betfriend messed around and she chose someone else and admited she used me. I didn't take it well but my other friend and a new friend helped me pick the peices up and things got cool between us all. Then me and that new friend spent the night at my other friends house. She wanted something. I gave it too her and today all my friends were telling me she hated me and crap. I talked to her. She admited it was nothing that she didn't care. Now I want to die more than ever. Is it worth it?
