Stuttering in a foregin language

Stuttering in a foregin language It stresses me out big time. My foreign language is actually english but when i practice pronunciation or speak to myself i hardly ever stutter. I don't remember myself stuttering in my first language. However when it comes to English and me having to speak to someone who doesn't speak my native language i (more often than not) just can't say sh*t. Do you guys have any ideas how to fix this? How do i not stutter? It's not that i don't know what to say it's that i just literally can't physically utter a word. My mouth muscles are like disconnected from my brain when i need to talk to a person in english
