head hunger vs real hunger

I need to get in tune with my band. I suddenly had some type of epiphany. I think since I have been stressed for the last week that I have been having head hunger. I just ate a yogurt and now am getting little rumbles in my stomach. I am concluding that I should wait until I feel the rumbles in my stomach to eat that way I will know for sure if I am actually hungry or if it is just my head playing tricks on me. I can do that or simply eat and snack when I am hungry but I don't want to go over my caloric intake. I feel really bad because I didn't eat much today and the fact that I am still up at this hour and hungry is bad. I really should go to sleep. I know I will have to talk to my doctor about this on the 12th of this month. today I am going hardcore on my exercising. I forgot to do some yesterday. I have to pull myself together. I've made it this far and I have a long way to go.
