depression is pretty common during pregnancy, I would discuss it with your doctor, she can refer you for counseling - which really does help.
Exercise really helps too, going for walks or taking a prenatal yoga class
I hope you feel better!
I know where your coming from, i have felt the same way during this pregnancy, i have cried, not been happy, depressed, angry, and just filled with so many different emotions i never noticed before, im usually a very positive person and i try and block the negativity, but it seemed that no one around me wanted to give me support.
My bf was just mean and annoying i couldnt stand him everything he did he bothered me, none of my family i felt like was happy that i was pregnant...
But, i relaized it wasnt them that made me happy or sad it was my own thoughts, i decided that i wasnt going to let their mood destroy me and my thoughts.. i just started looking up positive quotes, and self help books, i seperated myself from anyone who wanted to put their two cents in... and now im finally coming out of my funk and im so happy that my baby boy is almost here! Keep praying and keep ignoring all those that dont matter!!
