I was feeling exactly what you are feeling one week ago today, I would think of my kids and what if something happened to me and just cry. I was also excited for a new chapter to begin and knew in the long run, this would help me be a better mom! My surgery went fine, recovery went well ( day 2 was rough but I survived) and today one week out I feel really good, every day I get better and better.
The hardest part of taking care of my little ones is not being able to pick them up, but I sit down and have them climb on my lap to snuggle or sit on the floor to dress them. You will figure out what works best for you.
Good luck, it is going to be ok!!!!
