Godzilla help us... I just give up when I can and tbh you should try that, like becoming mute suddenly and using gestures instead, it's weird too but a weird I prefer. I know it's hard, you're stuck in the moment and it's like a matter of survival to finish it but imagine waking up in that moment and being like meh, then you look at the other person that's been waiting for you to finish, arm yourself with some righteousness then smile and wave or nod. Most times they understand. I have no trick if it's a conversation where you have to talk a lot though, I stop when I can stop and i say I don't want to talk rn or I try to focus, filter out the noise, try all the control tricks like breathing deeply, and produce something understandable, also I try to replace the anxiety with some badass feeling that I don't care what you think of me, Im doing my best so welcome to my world for a few minutes. I always leave with a bitter taste and random flashbacks when I'm supposed to relax but I try not to think about it in other words than, "not my fault, it's a disorder and I do what I can but sucks that people are shitty sometimes (when they are)" and I try to decompress, which I mostly fail at but I like the way I fool myself
