Please try this instead. Write down “I stutter and have difficulty getting my words out.” Show them that, make normal eye contact with pharmacist/cashier and start. Talking. Very. Slowly. I truly know how terrible it feels, but most people *essentially* walk up to pharmacists and say “I have a severe mental health condition, sexual dysfunction, hepatitis, terrible diarrhea, sexually transmitted disease, etc. While there *should* be no shame in those things, they are very used to talking to all sorts of embarrassed people. Also, if you *let ppl know* your stutter is debilitating and not funny for you, most people will be patient and/or kind. I hope you will try this and let me know, PM, whatever. I have been in your position and now enjoy talking in all kinds of situations.
