She is getting everything she needs - she is stripping it from you.
You need to eat chick! And maybe loot into taking a multi if you aren't eating much, as all the nutrients she needs, she takes from you.
Your body gives them to her first, anything left, you get.
You may find your nails and hair will get brittle first, split, your lips will be dry and itchy, your skin will get itchy and dry too. You may also start having issues like being tired, unable to concentrate, etc if you aren't getting enough yourself.

Even if you graze all day, get some raisins, mixed nuts like almonds and cashews, some yoghurt and some grapes or apples... Just pick, a piece of toast here, a piece of bread, whatever. But if you eat breakfast first thing, you will be hungry by morning tea time.

Took 3 weeks of DH basically force feeding me breakfast til my appetite kicked in.
