I know how you feel, mine progressively has gotten worse as I got older. It’s going to sound cliche probably, but your best bet is keep doing what you’ve been doing. It’s going to suck. There are days that are going to be a lot worse than others. That’s just what it is. Another tip, that may or may not be easy, but try to keep a positive mindset. Stuttering can lead us all, myself included, into a deep deep hole. At the end of the day though that only hurts us. Another tip! Works somewhat for me. Before any difficult interaction that you know of ahead of time. Take a deep breath and tell yourself ‘I’m the baddest mother(bleep) here.” It’s a mental thing, but it helps at times.
