Socially ashamed

Socially ashamed I’ve had a stuttering problem ever since I was like 3 years old and now I’m 25 and it’s gotten worse. I can speak three languages and my main language and home language was a problem at first but not English. Now English is my primary language and I stutter really, really bad in everything I say so I prefer to not speak a lot anymore. I feel awkward when I can’t speak to people. What do I do to overcome this?
