I have just recently developed a bad stutter, or slurred speech. (I dont know what to call it) Hello and thanks for clicking on this, I have developed a stutter (if you can call it that) over the last few months. It randomly kicks in, one moment I’ll be perfectly fine with my speech, but then I will randomly start mixing my words together and not mainly doing a “w- w-w- what?” (i actually do do it every once and a while) type stutter, but my words kinda blend together. I’m 15, and I get enough sleep every night. (8-10 hours). I have an extremely colorful vocabulary, and the problem is definitely not coming from not knowing the words. I’d say (humbly) that I’m relatively smart, and I have always been. Since about December of last year, it has gotten worse. My theory is that I think of words way too fast, and my poor mouth can barely keep up. The reason I say this is because I don’t think it’s anxiety (even though I do have a depression risk), because I’ll even do it in conversation with people that I trust and enjoy wholeheartedly. To anyone reading this that may know a fix and may know what’s going on, please leave a comment! I hope you have a blessed day! - Brodi Glenn
