Well, first of all I didn't go to my prom because I was over school by that time and i was "too cool" to go since I was already hitting the hollywood club scene - lol BUT I don't regret not going. We did attend some formals but it just wasn't worth it. I'm sure you'll make the right decision and you're not a bad person if you do go, just make sure its with another wit =)
*regarding college, its fun to go to community to get your general ed out of the way and then apply to university...by then you'll know what you want and if it's your thing....may the force be with you! ;)
