Try making online friends! Many people are supportive and understanding. If you're not sure where to start, join the stutter discord, there will be people there for you. From what I've learned about stuttering is that your mentality and environment can affect your stuttering. My parents tend to judge too, but it's whether you take their comments and plant them in your head. People tend to view their stuttering as a disorder and a bad thing, but if you see it as nothing or a positive thing, then it'll be better. Also, I really recommend doing breathing exercises! I'm starting to do the box technique and it allows me to breathe through my whole lungs. I have a whole spiel about breathing and why the box technique is good, so you can message me if you want to learn :)
