emotional ....

I'm 13+3 and I'm feeling so sad today , for some reason . First off , everything is irritating me (people's voices , phone ringing , etc.) noises seem to be bothering me lately. Second , I've been seeing women with cute bumps and mine isn't even showing yet . Lots of ladies seem to be feeling great and looking great ..not me ..I'm over here looking like I haven't slept in 3 months . I think that it's the lack of energy that has been getting me down . I really want to me out doing things and shopping for the baby, but I can barely even pull myself out of bed to come to work. I feel so down .
