Good for you for being open and upfront. It can be hard to get used to. I don’t think anyone likes admitting they aren’t “perfect” (whatever that even means). I find just letting people know takes the pressure off and it helps the person not be confused. Most people haven’t met someone that stutters before and are honestly not aware. I often bring it up or just say “I have a speech problem so you need to bear with me” on days when it gets bad and helps a lot. Confidence is a funny thing. I think we often blame things on our stutter that we may or may not have even if we didn’t have a stutter. There are many many people with no stutter that have very low confidence. My best advice is, act confident even when you aren’t feeling like it. Don’t feel ashamed and own who you are. And constantly tell yourself how amazing you are. Look in the mirror and literally tell yourself, out loud. And when bad thoughts start to creep in, don’t give them your time. Push them out, even if it feels like you are hitting non stop. It sounds like you are on the way there already and the more you do it, the more natural it will be. And if you run into anyone that is rude, don’t give them the time of day. Best of luck to you! Edit for typos. Probably more I missed :)
