Hey BrokenAngel1991,
If you are contemplating suicide, I sincerely beg you to seek professional medical help. Tell someone you're having these thoughts. I know I'm just some faceless person on the internet, and that discussing these sorts of things with friends and family can be scary, but you really should if you are having thoughts of suicide. If you need further counsel, you can always try Kids Help Phone. It's toll free, and it won't show up on the phone bill as "KIDS HELP PHONE" or anything like that. Sister, I know we may not know each other, but as members of the body of Christ we are intimately and spiritually connected; just as all Christians are. I genuinely beg you to seek help if you are feeling this way.
As for the topic at hand, suicide is a very, very serious sin. It isn't for me, as a human with limited scope and knowledge, to tell you what one's eternal fate would be if they committed suicide. That is only for God to decide.
Life will never be easy, but suicide is definitely never the answer. God loves you, the body of Christ loves you, and I am sure there are friends and family who love you too.
