Curious, I believe what you say, and I believe that because you did not have parents, God was there for you. I've heard stories like this before.
Do not deny him and do not let the witnesses twist God from you. They think they have the truth but they do not. God is like the God who met you when you needed him. He is merciful and warm and bright. The witnesses God is petty and legalistic. This is not for you. Please go to a regular church and join a study group. All you have to do is walk in and talk to someone. I am so glad you stopped the drugs. Don't start again. You can be an inspiration to others. Much love.
