I know everyone talks about stress, depression or any unhappy feelings leads to overeating, but I never "really" understood it until it happened to me. I always thought it was a lack of willpower on the person, but its much more complicated than that.
Now I wasn't going through anything traumatic, but I had was having a tough day at work and an overall stressful day. Suddenly deadlines, fire-drills, urgent projects, and my dog wasn't helping being mischievous every other minute.
I felt at my wits end. And all I wanted to do was eat. I felt hungry, even though I just ate, so I snacked and snacked and snacked.
Near the end of the day, I had an out of body experience where I mentally stepped away from myself and realized what I was doing.
My day wasn't going in a positive direction.. but what 'was' positive? The candy bowl in front of me, the chips and pretzels, etc. It was something I was "doing" that was "right". It gave me continuous "positive" reinforcement. I wanted more and more to fill the void of my crappy work day.
I now understand how a person can get lost in that. Luckily tomorrow, will be a better day, and all my deadlines will hopefully be gone, and I will need to workout to burn off all the candy I ate. :)
