How do you deal with the frustration?

How do you deal with the frustration? Ive had a stutter since I could talk, and thought I was doing good for a while. But I cannot take it anymore. I want to be able to speak like a normal person but I can’t. Im in my first semester of college now, and every time I speak I get weird stares from everyone around me. Every word I struggle on fills me with anger, and my anger keeps building. Ive beat my pillow more times than I can count. Ive punched a hole in my wall, and broken many things over my voice. What can I do to help with the anger?
