Everyone has a different reason. (Or atleast, most people). Sick of life Scared of life Don't feel they fit in Don't know what else to do Accidently (Yes, it does happen- they've only been trying to scare someone, to feel they care) Don't feel anyone cares
As much as these are reasons why people may choose to commit suicide, there are solutions to them all. Suicide wasn't the only answer. (And in God's opinion, wasn't the best answer).
