Hey girl, I know exactly what you're going through. High school was one of the worst times for me ( I'm 23 now ), basically because of catty jealous girls - just like the ones you're dealing with.
But this is the kind of stuff that's going to make you stronger in the long run. You'll find other girls who have the same interests as you, who you can connect with on the same mental level.
The only reason they care so much about how you look/wear your make up/etc, is because they know they'll never be able to achieve that talent. They have to tear you down so you'll be at their level, even though you're way above it. No matter how old you get though, girls like that don't go away. Like I said above, I'm 23 & I *STILL* have a girl or two who are "supposed" to be my friends talking crap about me behind my back...really hurtful things too. But you can't change people who are so insecure with themselves that they need to prey on the secure ones.
And just for the record, I've always been into make up & fashion, I was 13-14 years old & idolizing Pamela Anderson. As I got older, I started experimenting w/different looks to try & emulate my heroes. Of course girls never understood it & made their comments. But I didn't care, because I had perfected the "look" I wanted & felt beautiful.
And it did pay off, because now today, whenever I'm at work, at the store, getting coffee - wherever I am, I have people say to me,"I love your makeup! What do you use?" To me, that's the ultimate satisfaction & gives a great big "middle finger" to all those hater girls.
Sorry to rant, but this just hit close to home for me.
