Rahel,
A really good food to eat is pureed porridge. I cook oats with full cream milk for half hour so it's nice, soft and creamy. Put in blender with a banana, add mire milk and blend it. You can get the consistency that is comfortable for by adjusting the amount of milk. I had this for dinner every night for nearly 3 months. It's filling and nutritious as well. Hang in there, it will get better.
