BabyJane, hang in there, you may feel completely differently in 2 months. Everyone says having a child is a life changing experience and the vast majority are thrilled and excited when the baby arrives. I have heard over and over again that the child gives a parents' life purpose where they didn't know where they were headed prior to that.
I'm jealous. I've been sober for 11 months and I don't get a cute little baby as a reward!
I think many of us expected "big" changes at the beginning and as you get further into it all you realize that the little changes mean the most. Less drama and chaos, more things accomplished, better starts to each day, deeper sleep, clearer skin, etc.
Sometimes you have to focus more on the big picture than how you feel each moment. One of my friends used to tell his son "they're only feelings". They often pass, and your outlook can change the way you feel.
