I think you will regret suicide. The Lord calls some to suffer more than others for a reason, possibly so that it exposes another when you ask for help & maybe they don't reach out, or that it shows Christian strength when someone does.. in other words there is a reason for our suffering IT IS NOT IN VAIN.
Perhaps try an antidepressant of if you are genuinely suicidal, perhaps God is calling you to humble yourself to ask for intensive help, which is not easy. There are many reasons why we suffer.
PLEASE do not kill yourself. If nothing else post on these types of boards to ask for prayer & Holy Spirit Intercession. God created us for a purpose & HE Decides when our time to go is.. my friend in Christ, please don't do it. Know that Christian love is by faith not by sight & you do make a difference, it just not be as you can see right now. In Christ & for HIS HEALING Upon your life.
