PLEASE..ADVICE!!

Starja • First pregnancy and OCD doesn't mix so, I downloaded this app to calm my brand spanken new pregnancy hormones.
This is my FIRST pregnancy. I'm only three weeks and I can't eat. This is the first day that this has happened and I found out that I was pregnant from the doctor at a week and a half. I've had NOTHING today. Nothing to drink, eat, vitamin...nothing. I'm so ashamed of myself but, I can't work up the nerve to eat. I don't know what to do. I've eaten so healthy since I found out about my ginger snap. I love her so much though she's sucking the life out of me already. I'm so blessed to go against the odds that I was told my entire life and actually be able to conceive. I just need advice..
