Emotional Eating

Bad stuff is happening and it makes me want to eat. Not fruits and vegetables, JUNK. Its not even bad stuff that is happening directly to me, its just in the peripheral of my life and yet I still feel like I should eat. Where does this come from? Why can't I be one of those people who loses their appetite when stressed or depressed? At least I am recognizing it and staying clear from junk food which means I've come a long way. However, my first instinct is still to turn to food to make it all better (for a mili-second) - will this habit ever go away? Probably not, I am sure I will battle this for life and  I can only take it one day minute at a time.
