close to flatline

I am disappointed in myself.  We shouldn't neglect the things that we love. Running has been my love and I think it may even have helped save my life after my major emotional meltdown in 2007. However, I've gone from being lean and sharp to feeling like a bloated cart horse.
I finally went out for a run this afternoon after six weeks of saying "tomorrow"
I lumbered around in the ice and the mud for 5.4 horrible miles at a snails pace.
I wish I had a decent excuse but this has been pure apathy and now I have a mountain to climb to get back to and surpass my previous fitness levels.
I have decided to work out a training regime for three fortnightly cycles and then reassess.
