I'm trying to look for answers and I'm hoping you guys can help. Note before I start: I know I'm a young high-school student but I'm very aware of the difference between a stutter and just hesitating. I've looked into this the best I can and I've looked at the traits and different types of stutters which i have. Sorry for all that. So I developed a stutter about 8 or so months ago. It's a pretty mild stutter (I have small stutters almost every sentence sometimes). My stutter isn't consistent because most of the time I can go quite a long time without stuttering much at all but sometimes it's really bad. My biggest problem is that as of this new school year it has gotten a lot worse. It's used to be something almost no one noticed and now I have people pointing it out or ask if there's something wrong (which gets on my nerves because often times they're mocking me or making fun of me). There are sometimes that I'm stuttering almost every word which never used to happen but it's rare. I don't know if this is relevant but I also haven't had any brain injuries, problems, or some kind of decline of mental health (it's actually gotten better). Sorry I'm all over the place I'm just trying to lay everything out. But here are the questions I have I hope someone can try to provide possible answers. 1. Why might I have developed this stutter? 2. Do/should I see a doctor or get some help or diagnosis? 3. Is there anyway to fix or improve it? 4. Is it wrong or incorrect for me to explain I have a stutter/speech problems to people? 5. Is there a chance it will just keep getting worse to the point my rare constant stutters become common? Thanks, I'd really appreciate if you could help me try to figure things out. :)
