Sorry for your loss. Family comes in a lot of forms and it hurts just as much when we lose someone we care about.
Try eating some low-fat, sugar-free yogurt in the evening. The protein will help sustain you through until bed and the casein can help maintain your blood sugar levels throughout the evening. Protein-rich foods help keep you feeling fuller longer! Wishing you better luck at achieving your goals. Remember no matter what: You Are Beautiful!
