You have an awesome attitude, keep it up! I was in a similar position in college (I'm 30 now) but nowhere near as mature -- I drugged myself up to my eyeballs, partially due to my insecurity about my stuttering. It felt like such a crazy time where you are meeting so many people, getting out of your shell. I just keep putting myself out there and continue to desensitize myself and try my best to combat avoidance behaviorisms, that seems to help the most. Despite stuttering through it all, I have a great wife, a house, a good job, friends, the stuttering hasn't held me back. It only holds you back to the limit that you allow it to.
