See for simple stuff like picking up a takeaway, you could always give a fake name. I remember I was ordering coffee for my boss and used his name instead of mine, came out straight away. How old are you if you don’t mind me asking? I’m 23 and I’m finally starting to accept it and sadly my stutter isn’t getting any better but my outlook has. The reason it’s getting worse (in my opinion) is that you’ve had a couple slip ups and you’re letting it get to you which in return makes you anxious about it happening again. The more stress you put yourself under to not stutter will end up making you stutter. A vicious cycle
