Cravings???

I have had the weirdest cravings lately and felt really weird lately. I don't know whats up??? Maybe I just have bug in me and it is making me feel like this. Because all I want to do it sleep and eat ice cream and peanut butter cups. But I am trying not to let my body do that or let my mind tell me to do that. I am making my body go on walks and eat other things even if it makes me sick. Because I have to do other things and eat other things. Any suggestion???? No I am not expecting has far has I know. I just feel really weird and ache a lot lately. danielle
