For me, if I'm blocking on a word, I'm not going to get it. I restart my sentence (or part of my sentence) and try to push through it. The issue is that this is a coping mechanism as they say in SLP (I'm not an SLP but I've been to one). I can say with certainty that getting rid of coping mechanisms is a bunch of baloney. The big problem is when people avoid certain situations because of stuttering. I try not to avoid these situations, but it does give me great anxiety when I start to block and can't get a word across. If the person doesn't know that I stutter and I don't know them well, I try another word. If I know them well and I block for more than 10-15 seconds, I say "sorry, I just can't speak right now" and they always understand. I've been on the phone with people and I literally can't utter a word. That's probably the most embarrassing when they're saying "Hello? Hello? Hello?" We are the 1%. It's tough for others to really get what we go through because they've never had a problem talking to anyone. Must be nice.
