I've been crying since Saturday..

I'm 34 weeks and 5 days today and idk why but I feel so broken inside. I have no appetite and all I've been doing is crying, I cry randomly and I don't really have anyone to speak to. Only person I told about it was my boyfriend but he gets upset when he knows I've been crying.. I know it's not good for the baby but I just can't control my emotions right now. I feel fat, I feel ugly, I feel useless.. Has this ever happened to you? If so, what did you do to make yourself feel better?
