How is it that even when I’m surrounded by friends and family that I still feel completely alone?

I’m carrying my son...currently 33 weeks...and still feel alone...empty.

I don’t know why I feel like this. It’s not constant but it’s frequent. This is not new to me. Even before getting pregnant I would feel like this on occasion. Although, before I would just cry and go on. I can’t even bring myself to cry now. It just seems strange to me. I’m supposed to be more hormonal/ emotional now, right? Not less?
