Sleep deprivation always makes things worse, but I think I hear the anxiety I used to have when I realized that everything was on me. I used to wonder how I would handle things especially if something went wrong. Not having someone to back you up when you are a parent is scarry. I didn't feel that way when I was by myself. Just like I don't worry too much now because it is mostly me. "It's a parent thing" It will get better.
