Hello everybody, my question is how do you decrease (fight) stuttering.

Hello everybody, my question is how do you decrease (fight) stuttering. Hello Redditers. I am 23 years old and I stutter since I was 5 or 6. I am born in Bulgaria but I'm currently living in Austria and since I started learning the language (German) I have become very desperate with my speaking problem. The german language has a lot of sound that are very hard for me to pronounce and that makes my everyday speaking with friends, college's ect. very hard. I have tried searching the internet and reading about solutions but nothing works and I thought that if I recieve some advice from people in my position it will be more helpful and motivational. My question to you guys is how do you fight your stuttering? I mean what do you do to relax the speech and what kind of advice can you give me on my search for fluid speaking?
