How can I get over my fear of my stutter?

How can I get over my fear of my stutter? Hi there, I just stumbled upon this subreddit and figured I could ask for advice. I'm 17, a senior in high school and I've been stuttering my whole life. High school is about to end, and making friends, which is already very difficult for me, is about even more difficult. One of my biggest fears is my stutter; that when I go to talk to someone, I'll stutter right out of the bat and mess everything up from the start. How can get over this fear?
