I feel you man. Stuttering sucks so much. There’s no sugarcoating it, it really just sucks. I’m 22 years old, and I would say I have around a moderate to severe stutter myself. I don’t really have any advice or anything to give you because I’m pretty much in the same situation as you, but all I can say is just don’t give up. Miracles happen everyday. They happen EVERYDAY. You never know what tomorrow might bring, there might finally be a pill on the market, our advanced technology may lead to something coming out for this disorder, etc. You just never know. But don’t give up, life is too precious
