Sounds like you have a few stressors in your life right now!
One thing that I do when there are too many things pulling me down is to focus on my little one. Somehow that does seem to make it better. What I do is
- don't turn on the tv- unless we are watching one of his tapes and talking about it while it is on,
-don't plan on doing any chores- unless we do them together, like putting the laundry in the machine together
-play with his toys on his level (or up on his bed to compensate for the belly!)
-do a lot of talking about things in his life, understanding what the new baby will bring, etc.
-read books and tell stories
I find that he gives cuddles and hugs, and feels calm, in touch, understood- and that makes for a better, easier day of kid care! And it reminds me about the joys of being a mom, which truly are many, even when money is stressful and partners are freaking out. At the end, you have YOU, and you have the ability to make the little one you have feel secure and loved. And that can really be a lot! Sometimes an outward focus puts it a bit in perspective.
And then, when she is napping, you can do what you need to do, take care of yourself, or sleep, too!
I hope this helps! Although the attitude ebbs and flows, strength is constant, and you already know you have that!
