Oh purple try not to be so hard on yourself. In fact everyone needs to not be hard on yourself. Society has set us up to expect to be out and about at baby meets, that Breast feeding is the simplest way to feed your baby reading various threads I would say it's by far the hardest. Bottles are a faff yes, but so much easier to pin point the issues that you can bounce back to the pre baby you in the blink of an eye.
In reality, if your lucky it's a straightforward birth. If not, you need to deal with stitches, loss of blood, exhaustion from hours and hours of labour, lack of sleep, inadequate pain relief. I could go on but you get the drift.
There was clearly a reason why mums were kept in hospital for X amount of time. To minimise the amount you can do to let you recover. I have a friend who was out and about too quickly that her stitches burst!!
If you a ftm, it's a steep steep learning curve that no amount of reading/questions asking can prepare you for. I was certainly not prepared for the amount of crying I did. Those hormones!!
I'll be honest, the first few weeks I was just happy if I managed to shower and dress and get outside into fresh air. Trips to the supermarket were just about it bout all I could manage. It took a full 12 weeks until I felt more together. Even having a conversation longer than 10mins was hard going. Concentration span was shot!!
I don't know if it's been mentioned before but Google "fourth trimester".
Okay ill stop lecturing 
but I'm sitting in Starbucks with a child who decided to fall asleep just as I was about to go back to car! So nowt else to do.
