Skipped workout guilt

I just typed up and posted my workouts for the week. I missed half of Monday's exercise (I did the weights but not the cardio) and all of Tuesday's. I tried to figure out a way to catch up -- came up with a lot of plans that involved doubling up on my workouts on a given day, lifting weights two days in a row, or leaving for a run shortly after arriving at my aunt's house for a family reunion.

By Thursday, I realized it wasn't reasonable for me to make up the missed workout. I decided to just get back on my regular schedule and let it go. But I'm still feeling bad.

Part of me thinks it's ridiculous to worry so much -- I exercise 6 days a week most weeks, it's not a huge deal if I only get 5 workouts in every once in a while. That's my rational mind thinking.

My irrational mind believes this is the beginning of a slippery slope that leads back to tight-fitting size 14 jeans and an overall lack of fitness.

I'm guessing the truth is somewhere in the middle. And what I'm wondering is, how do I make peace with missing the occasional workout while continuing to push myself on a day-to-day basis? Where is the middle ground? I have to figure that out. Right now, my usual response to a week like this one is to say I'll put it behind me and do better next week -- that I'll complete all my workouts. And that's certainly what I'll aim for. But how can I learn to be consciously OK with myself if I miss one because life gets in the way? Hopefully I can come up with some kind of answer before I go off track again.
