"To the people I love..." Vent book and Why Teens commit suicide

This is just me ranting about my feelings, how people I love hurt me and just generally how I'm not mentally okay.
I'm feeling so upset to the point that I fantasize about how I'll get my revenge by committing suicide.
But my religion says no and I don't really look forward to burning in hell for eternity, so
here we are. A vent book to cope with my feelings and to tell people "don't do this, it hurts" and basically the few things I can't say to anyone else because no one listens and because I don't want to upset my friends.
