Me at 27, did speech therapy last year. I thought I controlled it, but you cannot win 100% from this. You will learn to cope with it, learn to face the frustration that comes with it. I don't know it sounds bad or good. But I am in that face. Sometimes I just shoot myself and upload on YouTube to fight my fear although sometimes I stops at the doorstep of a shop. It's just up and down, just try to find peace, try to get over frustration. I don't know much, but I think it can help
