Do you know about the parable of the drowning man? He took shelter on his roof during a flood and asked God for help, prayed every day for God to save him. People came by with boats, with rescue helicopters, etc to save him…but he refused saying that God will rescue him. The man drowned from the flood. The morale of the story is that God sent those people to rescue the man, and if he took initiative and saved himself instead of waiting for God to save him directly, then he would not have drowned. Applies for your situation too. You can’t rely on God to save you, you need to take control of your life and go see a specialist that can help you. A psychiatrist, a speech language pathologist, even a support group for stutterers would be helpful. (that parable helped me to take control of my life when I was still a Christian)
