I'm done with running

I can't do it anymore. I can't even walk. My knees hurt so frickin' bad. I thought a 2 day break would help. Nope, I'm on day 3. I can't carry my kids on the stairs. I have to walk down sideways. Bending down....forget about it. It hurts to even sit. The pain is keeping me up at night. This is even with regular icing and ibuprofen 800 BID. Mark's talking with one of his ORS colleagues to see if there is anything I can do to deal with this "runner's knee" and continue running, but most likely I'm done. I feel like such a quitter............and old.
