I am desperate. My stutter is getting worse.

I am desperate. My stutter is getting worse. I am desperate. I moved to another country and I speak English at work. When I’m talking to my bosses, I stutter a little. Earlier, I had a meeting with my clients, and I just stumbled at every word. I stuttered a lot. Saying “uhm” like 10 times before i can ever continue my sentence. This is very frustrating because I am in a professional environment. To ease myself from embarassment, I pretended that my internet signal was weak. They kept on saying “we cannot understand you.” I don’t know what to do now. I really want to lessen my stutter. I admit, I’m trrrified of meetings because I know i will stutter. Can you give me an advice?
