I agree truly. As someone who's also outgoing I try to engage with every conversation and like you said it looks like I'm having stroke. Sometimes I wish I could communicate telepathically or via text. And funnily enough I've had a lot of experiences where a conversation goes really well thru text like we could go on for hours but when we meet in person I'm dry as fuck. Sometimes I feel that my throat muscles are physically unable to function for whatever reason. What fucked up thing happened in my childhood for this to happen. Anyways, as for feedback I know that everyone is different but if it's of any help I recommend to just talk slowly and if you block or stutter on a word just take your time. I know how "unattractive" it may seem to look like you are having a brain hemorrhage but personally I've been thru this so many times that I no longer care. If they're impatient then that's on them, I highly doubt taking an extra minute in a conversation is gonna ruin someone's day to day schedule. And lastly if you haven't already just explain to everyone that you have a stutter. People actually have more empathy irl than you might think though it might not seem like it online. Also speech therapy. I haven't done it and have no idea how it works but that's what people say.... Anyways that's my dumb collection of thoughts. If it helps any amount I mostly feel the way you feel.
