I'm feeling much better. Mid-day yesterday the 'bad mood' lifted some, so I'm a lot happier. It's frustrating to feel out of control emotionally. With my history of depression, it's also a little scarey, so I'm glad to be having a better day.
I also started out yesterday feeling a little nauseous. I was worried that 'morning sickness' was going to start up again, but it only lasted a little while. I think it's related to the lack of space my insides have these days. I sit quite upright at my desk at work, and with the baby getting large (about a foot long now!) in there, not much space is left for my stomach. I found a smaller-than-usual lunch had me 'full' for quite a while yesterday.
