Hi jessesgirl
Baby blues is quite normal, I remember when I had my daughter in Oct last year, like you hospital was great, but when we got home I just broke down. The first week at home was the worst, I was just so emotional, overwhelmed and thinking about the huge responsiblity ahead, hoping that no harm would ever come to my baby, and that I would be able to stop anything bad from ever happening to her.
Just remember your hormones change after giving birth, and give you an emotional effect, one time you may be feeling down, and another, you may be feeling overjoyed.
Hopefully, your hormones will settle down and you can enjoy motherhood, it's a bit daunting at the start, but you soon get the hang of it and love it.
As for enjoying time to yourself, that's perfectly normal as well, you still need 'my time' after you've had you're little one.
Take care, and enjoy motherhood. If the baby blues seem to be lasting longer than expected, you should see your doctor though.
