Well your mind works quicker than your comprehension of it. You already have your opinion ready - that is how you feel about something. It’s never a problem to word something a second time, or to make a mistake. Everyone does! To stay with a particular opinion and socially defend it when it is challenged is always hard, but you can save yourself energy by discovering what exactly your opinion is too. Right now i just simply tell myself “hey im trying to have too much control” and sit back. I try to take in more what i hear and see around me and focus on those two items while having emotions come and go at a reasonable pace. Mind you also that a LOT of people have trouble and tricks when it comes to very specific topics, and nobody actually cares about a stutter when you have a good opinion and are courteous when challenged :)
