My stuttering got better after college. Speech therapy never worked for me. I think it was because as I aged I felt more confident, my self-esteem grew, I was at peace with myself and my life. With all of this, my fluency increased. Now in my 40s, I still stutter, but I talk all the time without hesitation or fear. If I went back in time and told my 16 year old self this, he would have never believed it. It will get better for you also, there is hope!
