I've been taking Salsa lessons for several months now. When I first started, I was so happy and into it. My life finally felt exciting again and I was very happy I started this hobby. But lately, it's been depressing me. I don't seem to be getting better, some of my dance partners and instructors criticize the way I dance, and worse of all, I don't seem as into it as I used to be. I don't understand. I was really liking this in the beginning, but now, it's making me more depressed than ever. Why is this happening?
