I keep telling myself I'm fine. But I can't even get through my own sun salutations without feeling that snap in my hip or just… wobbling. Like, I’m 47, I teach yoga, I should be able to hold a simple tree pose for more than 30 seconds without feeling like my knee is gonna give out. How am I supposed to teach people to balance when I can't even balance myself? It’s ridiculous. It's just... it's really getting to me.
