I felt like you when I was in college. I got tired of being scared to speak. After my first year I needed a job during the summer so I decided to bartend. I thought that would be a good job to have to get me out of my shell and I was right. You just repeat the same thing over and over again and it cured me of my fear of speaking. My speech and confidence improved 100%. Now almost thirty years later I can speak to anyone and maybe stutter a little bit but who cares.
