Do you guys have any tips on how to deal with girls who're mean? lol

Like mean lolitas or just mean girls in general? If it's the former, Lolita charm wrote a great article on the subject: http://lolita-charm.blogspot.com/2009/08/endangered-species-lolita.html#comment-form, and if it's the latter it's honestly a very similar issue. When people don't understand something or it doesn't fit how they thing things should be they sometimes lash out and say awful things. It comes from a place of ignorance and intolerance and nothing that comes out of the is worth listening to and shouldn't have any bearing on your enjoyment of anything. If you find it hard to ignore the comments try and find friends (especially some who share your interests) who will support you and can buffer out the negativity. When I got out with my local lolita pals I'm sure people talk about us, but we don't even hear them because we're too busy talking to one another.
