I felt that way in my teens and early 20's. I believe we all have a God shaped hole in our hearts, and only He can fill it. I met some people who had something different. A peace and contentment even during trials and tribulations. They told me about their relatioship with Jesus. I need to be free of my wrongs, to have someone I could trust completely and know they would never leave me nor forsake me, who would love me unconditionally. I could not find that person here on this earth. But I looked up to heaven and saw the cross, and asked Jesus to forgive my wrongs and come into my heart. I can't tell you how blessed it is to have a relationship with the Creator of the universe. I have survived tremendous difficulties and traumas because God was there to heal me and put me back together again. We are never alone, never without someone to love us, and never without someone to trust. He is God.
