I’m in the same boat, I have so much knowledge but I cant express it, my name starts with a hard vowel such as the letter D and when someone asks for my name I can’t say it as I have a 80% chance of blocking and when someone asks for my birthday oh wait same issue.I feel like I’m seen as stupid because people think I don’t know what the answer is to a problem or what my name is and I can’t even say happy birthday.I gained the skill of typing fast because of my stammer but I just know finding friends or a girlfriend is gonna be a great issue if there’s no one around with the same problem
