I'm also 5'2 (and a half - lol) and very skinny! When I started dancing, I was only 95 lbs (which sounds like a cow compared to you - hahaha). Despite all the praise everyone gives you for being skinny - I completely agree with you - there's a point where you're just too skinny and it causes problems with your health and energy levels. Dancing actually helped me to put on some weight by building muscle. It's hard to gain weight and eat healthy at the same time, but if you eat a lot of carbs and fat, you should be able to get to a healthy weight. I use a ton of butter and / or olive oil with everything I cook. I also try to eat a snack before I go to bed. Most importantly, you have to replace your calories every time you dance. A glass of milk will do it if you're not lactose intolerant like me. I don't really like drinking alcohol, but when I was living in Korea the only way I could keep weight on while I was dancing was to have a beer after every time I danced. I'm happy to say, that I've managed to get myself up to 115 lbs now, and I'm actually the same size as I was before - I just have a lot more muscle tone and have better energy levels. The good news is that it's cool to be skinny these days, so we hit the genetic lottery there!!! But, the point is that you being skinny won't be a hinderance to your dancing as long as you have the energy to do it, and dancing can help you to get to a healthier weight. ^^
