I also frequently miss out on social events because of my stutter. it's frustrating, and not fair. Especially because their isn't really a "cure" for it, and we all just have to accept this as part of ourselves. I find I do the best when I go into a situation with a idgaf attitude. Class presentations, job interviews, dates, are just easier when I psych myself up before hand. It's easier said than done, I know. And sometimes it's easier to cry about it and then go on living my life.
