Hi
Hugs from me too - I was also where you were when DS1 was born (he's now 8 years old), and I remember feeling overwhelmed, exhausted, knackered and completely useless. I just felt, who could I have gone through such a difficult, exhausting labour, and then be expected to care for a newborn, and feed him every bloody hour...
I did switch to formula at 10 days, because I simply needed sleep, and he was so so hungry. I felt terrible, and refused to open a card or present for three days, as I felt that I had failed him.
In the long term, it was the right thing to do, though. It was still hard going, as he was very colicky, but I did get some sanity back. With DS2, I was much more on top of it, and did exclusively breast feed.
You useless midwife will sign you over to a health visitor in a few days - in the meantime, you must do what is right for you. My HV was understanding. She told me a few years later that they were really worried I was going to have PND, but it was just exhaustion, and a certain amount of post traumatic stress after the labour.
If you do choose to continue breastfeeding, make the most of your OH being at home, and have a few days just in your PJ's, in bed, cat napping when you can. I PROMISE it does get easier - the first few days are hard, by two weeks, you'll be feeling a bit better, and by three months you won't recognise yourself.
Take care.
