Feeling like crap.

The past two days has been rough. My self-confidence has taken a serious dive and I just want to curl into a ball and cry myself to sleep. Yesterday someone asked how far along I was, and I told them almost 18 week, and he just looked me up and down and said "huh, you don't really look pregnant". I KNOW. I LOOK FAT. and my little four year old, bless his heart *twitch*, has taken to calling mommy fat everytime he sees my belly. All day I've felt uncomfortable in everything I've worn, and when I mentioned it to my husband, he just shrugged and reminded me that I'm pregnant. I KNOW! god, do I know. What do you ladies do to make yourselves feel better when you feel like an ugly, fat cow?
