Eating only 600 calories a day is obviously not healthy. If you can't bring yourself to really eat in the morning maybe try to have a protein shake (can be only 4-6oz) or one of those morning carnation shakes.
I ususally try to plan out my food the night before so I know exactly what I am going to eat the next day and I know that my percentages are okay. I put all this food in my lunch box and eat on it throughout the day. I know that by the end of the day the food should be gone. Perhaps this could help remind you to eat and how much!
