Do you have anxiety even when you are not nursing? If not, I am wondering if you are just feeling the true stresses of the responsibility. The first month were two are probibly the hardest two month of my life for each baby that I nursed.
I did not have a strong support system for my 1st child, so I pumped a few weeks then went to formula. But I was determinted with my 2nd, and prepared an armory of experianced caring people and nursed her for 14 months. Now with my third, 5 months into it I still have questions and concerns, but I don't "freak out" as much.
As wonderful and rewarding as it is, and it gets soooooo easy after the first month or so, it is one of the most trying times in a woman's life. With each child, a couple weeks post partum, I have had a break down just sobbing in the shower. lol my husband always walks in concerned, asking whats wrong. with the first baby, it was I DON'T KNOW! All the way to this time where i whimpered, "I feel like my body is so out of control and I will never get sleep, and I don't even have time to wash my hair! But I know that it will be over and things will be back to normal sooner than I can imagine." and he looked at me and said... wash your hair : lol
What I am getting at is.... If it is not a clinical issue that exists outside of post partum, then you are not alone. And if you need any support feel free to send me a message.
