The sleeplessness and the out-of-whack hormones are NOT helping things right now, I'm sure. Turn off the news and ignore the stuff that you can do NOTHING about, like stock market issues. As I've seen from my own very negative DH, that stuff can really bring you down. This is a particularly difficult time for EVERYONE right now, not just you.
Things will definitely get better. And then they might get hard again. Life with children is definitely not easy. I guess the trick is to try to see past the immediate ups and downs and realize that all-in-all, things are pretty good. Of course that's much easier to do when you've had some sleep.
" I object to violence because when it appears to do good, the good is only temporary; the evil it does is permanent." Mahatma Gandhi
"This is the ultimate weakness of violence: It multiplies evil and violence in the universe. It doesn't solve any problems." Martin Luther King, Jr.
