Hi, I can totally relate to you! I am also 23 and have been stuttering for as long as I can remember. The past few years it's gotten really bad. I believe it's because I've become more independent and had to venture out on my own (adulting). Some days I feel so isolated from my friends and family, especially when they're having a discussion and I can't join. I find that I am becoming more of a quieter person and not as outgoing as I used to be. I feel that each year I lose confidence and just want to shut myself away from the rest of the world just to save myself from the humiliation and shame. I know this is not helping but I just wanted to let you know that I totally understand how you feel.
