I can’t say my name sometimes because of my stammer

I can’t say my name sometimes because of my stammer I have a covert stammer so can hide my stammer a lot of the time. However, when I try to say my name sometimes or try to explain what I do for work, that’s when it comes out, and it’s so degrading. Tonight I pre-ordered a Chinese takeaway to collect. When I got there they asked for my name and I literally could not say it, I had to turn to my partner and ask him to say it (that’s the worst it’s been). I’ve always had a stammer but it hasn’t been this bad or had this much of a negative impact on me for years. It sucks. I’ve got speech therapy starting next month and I am on my third week of 50mg sertraline (my stammer has now made me socially anxious/avoiding certain social situations).
