I'm exhausted I am not the type of person to keep someone entertained for hours even before I was pregnant. It's a lot worse now. I am not a recluse but my best friend is my husband. I don't go out to make friends. I like people don't get me wrong. I'd rather sleep right now then have company over or talk endlessly. I know that sounds cold but I am worn the heck out. Anyone else like this?
