Feeling miserable and depressed.

I'm so glad to be pregnant. I really am and I'm so so grateful, but the past week or so I've been really depressed and just want to cry. I feel pathetic. I haven't made dinner in over two months because I can't stand most food and handling it. I have zero appetite. When I do have an appetite all I can stomach is ice cream and hot pockets. I don't want to go anywhere or do anything. Nothing. I already suffered from anxiety and depression long before I was pregnant so I'm sure that's a factor. But I just feel completely pathetic and stuck. Anyone else feel this way?
