I only occasionally get a very bad stutter. How do i keep from wanting to bang my head into a wall every time I try to speak? Sorry if my words dont make sense, I’m dealing with several cognitive issues right now. I am highly sensitive to medication and this week tried out a new inhaler that immediately messed me up. I am now struggling with both word recall and getting words from my brain to my mouth, among other issues. I get so frustrated so easily with my stutter, it’s only been this bad once before. I am also so fried from all my other symptoms right now, I feel like I’m going to cry while at work trying to talk to customers. I feel like such a kid, my tolerance for emotions is way limited right now. Any advice for how I can survive riding this out until I’m back to my normal?
