Worried that people may think I’m faking my stutter

Worried that people may think I’m faking my stutter I’ve been stuttering for years and my stutter is very unpredictable in its nature. Some days I stutter, other days just a bit or maybe not at all. Sometimes I may manage not to stutter on ‘a particular word that I usually find hard to utter.’ I had several phone calls this past month with the same person and they pointed out how I “no longer stutter anymore” when it just happens that whenever we decide to speak on the phone, I’m having a ‘non-stuttering day’ (I refuse to use good/bad speech day). I got comments like this before! I spent hours paranoid and thinking what if they think I’m faking it? Can you relate? *I hate that I even have to explain myself. I think it’s very unnecessary to even make any comment about my speech, whether I’m stuttering or not!
