Did a presentation and stuttered horribly

Did a presentation and stuttered horribly I’m a freshman in college. We were required to do a presentation if our philosophical papers, and I stuttered every second during my presentation. It calmed down when they started to ask questions and add comments. I feel so bad because I stuttered so hard it was insane. I feel like they are weirded out because I have a stutter. My stutter is minimal when speaking to professors, friends, or strangers. But it aggrivates when I am perceived by many people or when I am nervous around someone. How do you fix stuttering? I badly need help.
