Frustration....

I should have been out training this am but due to a procedure I had yesterday I am not supposed to workout for 7 days.  Even though I understand why it is still totally frustrating that I just started this 5k program a week ago and already something has gotten in the way.  Part of the problem is I feel totally guilty when I don't exercise, even when it is for good reason I just feel like I let myself down.  Does anyone else get these feelings of guilt when you are unable to exercise??  It is truly like an addiction to me, probably not a good one.  If I workout today I run the chance of ending up in the hospital later.  To keep myself busy I went and had a mani and pedi, lol!!  It felt nice but still isn't the same.
