Stutter making me sound mentally impaired?

Stutter making me sound mentally impaired? Hi everyone, happy new years! I just wanted to share a personal experience that I have struggled with. So my stutter is less repetitions and hard blocks and more so elongations and abrupt or slow, 'janky' speech (perhaps a technique used to avoid hard blocks). Due to these speech issues I seem to give people the impression that I am slow or mentally impaired when I first talk to them. I think it maybe even worse than having a visible stutter/block as people don't even know its a speech impediment. I think part of the problem is that due to my stutter and lack of complex social interactions I have also learned to talk in a very scripted way that comes across as simplistic and lacking depth. I have been trying to change the way I talk but haven't had much success despite really putting myself out there and trying to talk to more coworkers and random strangers. I wouldn't say this issue is crippling or really impairs me but it does seem to always give off bad first impressions when meeting new people and more often than not kills the vibe for any meaningful conversations. Does anyone else deal with this problem? How have you come to terms with this issue or do you use certain techniques to deal with it?
