it is ok ! you are ok ...you had a very fast delivery, and porbably still adjusting , you might be a little bit shocked by it all!
it is ok, you can cope, you will cope
as mrsdarcy has said, the 3rd day post delivery can be hard, as your body realsies it is no longer pregnant, there are massive hormonal changes, and your milk comes in too!!
is your DH around?
have you friends and family you can call on ?
make sure you get some help with the practicalities, of shopping, cooking, cleaning etc, so you can enjoy your baby
sounds like you have had no time to adjust....
induced, no contractions to indicate things were happening first, then wham bam ! baby ! and then home barely 8 hours after getting to hospital....
no wonder you are reeling
