hello thats relatable i use words that are close enough all the time and end up in really embarrassing situations because i wont register that i used the wrong word ive learned some coping mechanisms though that work for me  1 i slowly repeat questions before giving my answer it can feel awkward to do but the amount of time is short and it helps me focus my brain no ones ever commented on it before  2 i jot down a conclusionkeywords before i speak that way when i am trying to get an important point across i can make sure not to get sidetracked and that i hit all of the issues that matter  3 i try to remember that my brain is zooming and everyone elses is likely not i slow down speaking a lot and i pause between sentences to focus on 1breathing and 2 what i am saying and not being distracted by my voice or whatever  but like all that said i still get frustrated as fuck when im talking to people and i get too overwhelmed by my thoughts and cant say anything coherent at all if im not prepared for confrontation
