Stutter gets worse when hearing other stutterers speak. How do I keep myself from stuttering more???

Stutter gets worse when hearing other stutterers speak. How do I keep myself from stuttering more??? I can’t watch some movies and shows like It. Being around other stutterers makes mine worse. Even watching Animaniacs makes me block because I start to accidentally mimic Yakko’s “uhhhhhh” and I takes me a long time to get passed that block. I’m sorry if this has been asked before but I’m getting frustrated. I’m trying to stay relaxed but it’s embarrassing taking phone calls at work and failing to properly socialize with people. I thought I got passed the embarrassment since I’ve stuttered my whole life but it’s getting bad again
