Dear Maggie: Does masturbation discount me from church?

I’m a constant failure when it comes to Christian discipleship. I have been forward for prayer so many times about stopping masturbating, repented and asked God to help me, but then I go back to it – I just can’t sleep until I do. Is it dreadfully wrong to masturbate? I’m single, very active in my church, but feel like such a hypocrite. Maybe I should pull back from church?
