Depression?

Olivia
Hello. I am 12 weeks and 4 days today. I've had terrible morning sickness but it's finally starting to ease up. However, I'm starting to feel super depressed and have lost all motivation to do anything! I'm either crying for no reason, isolating myself from my husband and family, or I just stare off into space because I don't feel like talking! I know this is supposed to be such a happy time but I can't seem to beat this depressed feeling. Anyone else experienced this? And what did you do to get your spirits up?
