Dancing in high heels is kind of tough. I learn the dances without the heels, and then we add them. We just practice, and I get used to it. My feet hurt really badly at the end of the shows, but it's fun. While it's happening it's fun. I feel tall.

I can't stress to you enough how much I can relate to teens being cyberbullied. Something that helps me is looking at old videos of me and my friends from middle school, or videos of my family. I love watching funny videos of my favorite people - it really cheers me up.

The thing about dancing - what it taught me all those years - is it gives you an amazing sense of discipline in forcing yourself to do things that you know are good for you but you don't really want to do.
