Stuttering + Reserved Nature

Stuttering + Reserved Nature Im losing my mind recently. Before summer started, I did have a stutter and it limited me very briefly on certain things such as phone calls and interviews, but recently I feel like my stutter and reserved type personality are joining forces, and I can't even get myself to open up to others due to my fear of stuttering and my fear of oversharing, even to my close friends. It's so hard to explain. It is strange though because its almost like I'm watching myself make this unwanted change and I can't figure out how to reverse it. I don't know if I'm looking for advice or just someone else with a general understanding. Thanks for reading anyway.
