First off, you have a right to communicate how you can. This is something I’m still learning to grasp, but honestly, repeating affirmations when I feel discouraged has helped. I tell myself that I am brave for continuing to speak, that I am courageous for having survived everything so far. I tell myself that I matter just as much as the next person, that my words and thoughts and opinions are valuable. It helps, a bit. If we only listen to the negative voices in our head that tell us we suck, that’s what we eventually believe. Another thing I’ve done is to straight up tell people that i stutter. It takes pressure off of me from trying to hide it, and the person I’m talking to usually stops interrupting as much. If it’s someone I know, like a friend or family member, ask them to not finish your sentences. I know they do it to try and help, but I’ve had to have that same conversation with friend, coworkers, etc.
