I want to accept my stutter without letting hateful comments get to me

I want to accept my stutter without letting hateful comments get to me For a couple years I’ve been “suppressing” my stutter bc I didn’t want my bf to make fun of me, but he says it’s cute so I try not to avoid it around him. When I began to allow myself to say what I need to say with a stutter my dad mocked me from the other room so I started avoiding it again. I want to learn how to be confident in how I talk, and come to accept my stutter bc trying to avoid it is mentally exhausting and most of the time if I feel like I’m abt to stutter on the beginning of a sentence I js won’t say anything. I’ve been trying to watch videos from stuttering advocates and stutterers so I can feel more comfortable. Idk if anyone can help, but if there’s someone who can I’d appreciate some advice
