You recognise that you are eating for comfort so maybe think of some other comfort measures you can take - paint your nails, ring your Mum, have a long bath - whatever works for you.

Maybe keep a food dairy for a while and don't just write what you eat, write why you ate it. How were you feeling? What were you doing? What was your inner dialogue? If you can examine your eating a little more closely you might be able to find ways to a healthier relationship with food.
