I do not believe suicide will send you to hell. I am hoping linen53 stops by here, as she has a very potent memory about what happened after she committed suicide.
I am not saying that to rest your mind, but to enlighten you. Often when souls die prematurely out of suicide, they give themselves an even tougher lifetime the next go 'round.
There are a lot of benefits to living in this lifetime as well as well as pitfalls--focus on what you like about this time frame rather than what you hate about it.
You think hateful nasty thoughts about this lifetime, that is what you will attract. No matter what the situation, whether you can control it or not, you have a choice to be happy. One of the hardest lessons to learn and I am still a ways away from perfecting it.
