How do I stop stuttering or reduct it a lot?

How do I stop stuttering or reduct it a lot? I've struggled with stuttering my whole life and it's gotten worse over the past 2 years. I've tried pulling my words, jaw technique, and diaphragmatic breathing, but it doesn't work. When I talk to my friends online I still stutter but when I talk in real life my stuttering is a lot worse. Can some people please help?
