Dang it all!

Today I used a rest day from P90X, and did a little stretching of my own during the day.  Unfortunately, I decided to injure myself in taekwondo class today.  I'm not sure if I'm training too hard, pushing too hard, doing more than I can handle... but I hurt my groin this evening, almost pulled my hammy, and aggravated my old foot injury again.  It was a great, fun class, regardless.  I really enjoy martial arts, can't say that enough.  I want to be great, and I think I'm taking my pursuit a little too fast.  Can't be great if I'm injured :(  Guess I'll need to take it down a couple notches, heal up, and do what I can, when I can.  Thought about going to the doc to have my foot checked out, but I haven't gone.  It seems that just when my foot feels good I go and do something to make it mad.  Very frustrating...
