I have speech issues too and I totally get you. I mumble a lot, mix up words and most of the time people don’t get what I’m saying or rather I’m not able to tell them what I want to say. I speak two languages but my written skills are way better than my spoken skills. I’ve lost confidence over the years due to this. Hence, I too am the listener, the quiet boy. But it’s great to read about how you got through this. Happy for you!
