Well I mean we can’t exactly diagnose anything, we can only give input on what we know and what our experiences are. I’d highly recommend seeing a psychiatrist or a neurologist and seeing if there is an anxiety disorder/how to approach treating it. Even seeing a PCP can help you by prescribing an anti-anxiety medication. Based off of what you said above, it doesn’t sound like you have a stuttering problem, but the stuttering is a symptom of something bigger. Best of luck for coming out! Never be afraid to tell people, even your parents, about who you are :)
