I’m a guy my man but it doesn’t matter why or how you were born that way it happened you can’t change it so it’s best to figure out how to live with it and idk if you do this but for me reading out loud/singing has taught me how to find my voice when I find myself struggling to get words out in conversation. Record yourself on audio and or practice in the mirror talking to yourself another tip I’ve developed is the 5sec countdown if someone asks you something think of the response count down then answer. My speech was shit and still is some days but now that I’ve been working on it every day life’s been so much easier it takes time and a lot of effort. Not being able to speak is something normal people won’t understand so u can’t be mad at your parents or anyone without the issue bc they just have no idea what’s happening but it doesn’t give them a right to be shitty towards you though that just makes them assholes
