It's terrible when your child gets sick. I know it is a big adjustment in your family meals. I'm allergic to chicken, so I kind of know how you feel, though not as much as corn. You will have to be creative for her to have treats.
I know you are feeling down but you have a lot to live for: a wife and child that need you. I know that doesn't make the feelings go away. I had those feelings just a short time ago and only little change in my meds helped me out. Hold onto those you love, there life would be ruined without you in it.
