Yes, Jesus showed us by His resurrection that there is life after death. We all have a soul, and it lives through eternity. The only reason people miss heaven, is because sin separates us from God...but when we ask Jesus to come into our heart and life as our Savior and to forgive us of our sins, he does that, and we come back into fellowship with God. Then He sends the Holy Spirit to live in you to help guide you through life. He also gives you the free gift of eternal life. He gave us life for a reason, and that was to live it, not kill ourselves. So the answer is never suicide. There is nothing too hard for God to accomplish in your life and give you a brand new start.
