I get like that too. I know that I should be eating, as I am quite thin, but I can't be bothered. I have learned to love myself by making myself a protein shake. It gives my body what it needs, and tastes great.
1 cup of milk
1 scoop of chocolate protein powder
1 banana
1 hand full of frozen berries
A few ice cubes.
Blend and enjoy

My comfort food is homemade mac & cheese casserole. Yum
