The more you fight stuttering, the more it will likely increase. When you stop fighting, let it happen, and be ok with talking and stuttering, the easier things will be. This is obviously much much harder said than done and a truly qualified speech therapist can be a big help. One who doesn't focus on fluency. But my advice is don't aim to achieve fluency. You are a person who stutters and that is perfectly OK. Instead focus on saying everything you want to say and let the stuttering be as it is.
