Pregnancy depression of some sort?

Hi,

First I'll start with a little bit about myself...I have been know for being so positive at times people actually get mad at me. I have been depressed before but have always been able to work through it pretty fast.

At this point my last month was extremely difficult. I was so self conscious, moody, and didn't really talk to anyone about it. I also was dealing with some pretty terrible pregnancy rhinitis that aided in a no sleep regimen. Anyway, does anyone else feel totally alone sometimes even though you might have every support system possible?

I am doing better but it was strange for me and I just wanted to see if anyone else has had similar feelings? Thanks
