You have a whole life ahead of you, Jess. Why give up now? What exactly do you have to lose? Life is only one shot. Suicide is a permanent solution for a temporary problem. Don't give up now. Your life has barely begun. Think of your future and what you can make it be. The pain you feel can be overcome. Three years is long but it's not long enough for you to just throw your whole life away. Wait until it gets better and see what happens. You have nothing to lose. Suicide you do, but waiting around longer you have nothing to lose.
Don't kill yourself, Jess. I'd honestly be hurt if it happened. I know a lot of members on this site would be too.
