All I can tell you is try to avoid what I did - at university I was so afraid of stammering saying my name when introducing myself, that I avoided talking to people altogether. This meant that I made next to zero friends in the class and my grades suffered as a result. If I was more OK with stammering then things may have worked out differently. I was afraid of being the guy with the stammer so instead I became the guy with no friends. I'm now 30 and thankfully life and work is much better.
