Have you ever thought you had PTSD from stuttering?

Have you ever thought you had PTSD from stuttering? I took a few pstd tests and a lot of them usually are mid/mid-high chance of ptsd. I have a stammar not a stutter (block) by the way. (Heres a example of why I think I may have it) I always dread going back to the first day of school (I'm a senior now) because if they do the thing where you have to introduce yourself, you're mind goes blank and you sit there just staring, trying to speak while the class thinks you're on drugs or something, and it feels like time just slows down like a movie, the only reason why im scared of school is people wanting to talk to me and i'll sit there like, (Oh hi my name is...........). And back when i was a kid my step mom also said I had mental problems because I had to take medication (I also have Adhd and maybe even ocd) It also doesn't help that I really only have a few good friends I go outside with too. Sorry i kinda had to get this off my chest but does anyone else feel like they are like, traumatized by their stutter/stammar?
