Yes, unfortunately I've had to cancel all of my races so far this year, and am hoping to be able to finally compete again in July. I injured my left quad back in March, and am just now able to actually do something on it. So I do feel for you. It's hard to sit back and watch your friends doing what you have worked so long and hard to do. For me, it was especially hard because I was moving from AL to TX in May (just finished, in fact), and wasn't able to do one last race there, including the first one I had ever competed in. It was tough, but I made it through it. Now I'm just focusing on retraining myself, and trying to prevent it from happening again.
