God wants to use you for his greater glory, to exist in a relationship with Him. But suicide is not part of His will. If we are told to choose life, (Deuteronomy 30:19) then that goes for all phases of life. Whatever problems you have can be overcome with the Lord's help: "Blessed are the poor in spirit, for theirs is the kingdom of Heaven." (Matthew 5:3) If you feel life is not worth living, seek the help of Biblically-based counselor and allow God to show you His love and His plan for your life.
