Do I give myself time or do I push?

Trying to decide, how much do I push.  I am thinking I am trying to put too many goals in place right now. One of the things that I am doing is making a weekly goal. 

My goals this week are to eat 2 pieces of fruit while at work; this is attainable.  My other goal for this week was to walk the parking garage twice this week.  I realized that this goal is sort of attainable.  I have appointments the rest of the week and I am hoping to have lunch on Friday w/ Kat and the twins.  Given that, it seems today is the only day I could walk, and I don't feel like it. 

I didn't walk, instead sat at my desk reading.  Also, while having a very good lunch of salad, went and bought trail mix and ate the whole package :(  Really fighting the munchies again.  Oh well, I just keep plugging away towards my goal. 

This process must be one of the most demoralizing processes out there.  Talk about feeling like a failure if you can't do it. I mean, its just food right?  How weak are you if you can't resist food?  There is so much revolving around this that makes me feel less than it is exhausting.  I'm tired and dragging.  I just want to curl up in a ball and hide.  I want to pull in my family and just hibernate.  Can't do it, but it would be nice...
