True Confessions: A Rut

I wasn't going to post today, but I'm feeling very blah and needed to get a few things out (at least what I can get out in a public forum like this).  

• I'm in a rut.
• I'm fueling my body (and I use the term "fueling" very loosely) with crap and my scale is reflecting this. (Case in point: McD's fries for lunch today.)
• I'm the heaviest I've been in probably 6 months.  Not by a lot, but enough that I'm over what I consider my "danger" weight and I feel gross right now.
• I've run a whopping 18 miles total since my marathon on October 16th.  (To put it in perspective, I hadn't run less than 18 miles in a WEEK for the three months leading up to the race, except one week when I was horribly sick and only ran 4 miles.)
• I also haven't been doing really any other workouts.  I've biked once or twice, done a couple NTC workouts, but that's it.  It's no wonder I've gained a couple pounds and probably lost massive amounts of muscle.  Eating crap + no exercise = a fat, depressed, Bari.
• My Tinker Bell Half Marathon training is supposed to start this week.  Tonight should be my "first" run of 40 minutes and this Saturday my "first" long run of 4 miles (if I follow the half plan from a year ago).  Should be easy, right? But my runs lately haven't been very easy.  I really wish I had a training partner for this, because the thought of training by myself this winter makes me sad.

If anyone would like to run with me this afternoon/tonight, please let me know.  I'd love the company.
