i’ve been the same way. my speech is so bad around friends and family, but around strangers it’s better (usually). it’s so strange. recently i’ve been trying to more upfront about it. here’s how i imagine it: you know when you break out really bad and try to cover it with makeup and it ends up looking worse??? that’s how i try to think about it. yeah i have a massive zit on my face, oh well i’m not gonna bother trying to cover it. yeah i have a stutter sometimes, whatever. and then over time you won’t be so focused on your speech. just like how over time you won’t care about a breakout as much. i’m still in the habit of trying to hide or suppress it, but im trying to work out of it. hopefully this helps a little bit. :)
