I want to reinvent myself this summer?

So as a little kid, I was pretty normal. I've worn glasses since I was 2 and I'm almost 15 now. In 4th grade, I got an awful haircut and I let my mom pick my clothes out because I was a tomboy and didn't care. I got a little weird then, but I was confident so I got along well with others. In the summer before 6th grade, I somehow convinced myself that middle schoolers were giggly spazzes. Everything I wore HAD to be pink because I was a girly girl. About halfway through 7th grade, I finally ditched the giggly spaz thing, but I think I was still kinda annoying. I lost ALL of my confidence in 8th grade because my dad became even more verbally abusive than usual. I was very quiet and didn't talk to anyone outside my circle of friends. In 9th grade... ah. We left my dad in December and I started getting my confidence back. I realized my goals of being normal were unreasonable and that I should embrace my individuality. I'm getting contacts this summer and I really like the scene look and ideas. Help? :)
