I had a real experience with God's spirit and I believe he is active in my life.
I'm happy for you. I don't think that there are many people who have shed more tears and prayed more earnestly than I have or have came closer to committing suicide than I have only to experience absolutely nothing from a nonexistent God. I did survive through perseverance but not because of any God who could not give a shit about my welfare.
But that's not the reason for my being a nonbeliever. Become a critical thinker; question everything. You'll find that the arguments presented by believers are based upon faith. Don't overlook the possibility that your God experience could have been caused by some rational explanation.
My son was a drug addict off and on for many years. Toward the end of his life he told me how he had talked with God. It was real to him.
