I've always suffered with a stammer I had speech therapy and it helped to an extent but its still hard even now to string a sentence. When I'm in conversation I tend to repeat myself a lot if I can't get out what I need to say. It makes me really self conscious. I find sometimes singing helps and it's one of the ways I can get the words out without having to say them. Again you can't go round singing at everyone lol. I find saying the words slower help too, but it's kind of something you learn to accept but I can see frustration it causes
