(27M) also have a mild stutter, Mine's inherited. I also block, Repeat parts of words and prolongation. I have similar problems with getting people's attention or even saying my own name it just doesn't want to come out aha. I've found the best thing for my stutter is just getting out of my comfort zone. Being around new people, Talking to strangers. Yeah there's going to be some awkward moments it's just about trying not to beat yourself up about it. A stutter's worst enemy is themselves I reckon. 🙂
