Frustration and Motivation

I've been back in school for two weeks now, and it has completely thrown me off balance. I think my training has been the thing that has suffered the most from my lack of equilibrium, and I'm trying to keep myself positive and work through. I keep having to remind myself what I'm doing:
1) learning how to run properly so that it can be something I can do for the rest of my life
2) becoming less of a headcase and finding a balance in my life that involves exercise
3) becoming healthier
4) taking the time to work through some old cobwebs and cleaning them out, so to speak
5) running the NYC Marathon.
Doing this involves less of me beating myself up and more of me relaxing and taking things in life as they come. I'm noticing that my training has been pretty cyclical, and when I'm pushing through tougher parts of it, I tend to blog more, but that's what the blog is here for. I started out with a lot of fears and anxiety about my training, and wasn't terribly consistent. Then I hit my stride and began making significant mental and physical gains. Now I'm back to fear and inconsistency, but I'm trying to keep it in perspective. I've had a bumpy last few weeks - I had my 13 miler that went bust on the Brooklyn Bridge, then a 14 miler that I finished but was not particularly pretty (and took me a while to recover from), and then last weekend's pacing disaster. So it's little surprise to me that I've been a bit anxious for this weekend - at most, I'll end up doing 16 miles, but more than anything I want to be strong and consistent throughout my whole run. On reflection, though, I think that's the essence of training - forward progress, finding yourself in uncharted territory, overcoming fears and anxiety about said territory, and then making more forward progress. I will get back into balance, this is just another hill that will make me stronger.
