Re: Boo sensitivity and insecurity. Help?
have you thought about joning a social organization, like a sorority? i know there are a lot of myths about sororities, but they can be a great way to interact with a lot of different people. not all sororities are created equal, so there may be one that's right for you. i wasn't in one, but my husband was in a fraternity and it gave him the opportunity to build leadership skills and he made some great life-long friends.
i know it's an awkward time, still. i was kinda like you throughout college, except i was able to have interaction through my husband's fraternity...and i ended meeting a few friends myself (girlfriends of the fraternity guys...who are now the wives of these same guys).
i also took the opportunity to take some speech classes (not required courses) to help me build confidence. public speaking really sucks, but since my grade was dependent on how well i did...i tried my hardest, and i ended up doing really well.
anyway, i hope these tips help you. just remember, there's nothing wrong with the way you are because everyone has insecurites. but, i find it admirable that you are wanting to work on your insecurities and that you want to make the most of your college experience.
