Thanks @Madagascary. Things are ok here. Still very tired from the general, but not much pain (day 4/5). Boobs are a weird shape, but thanks to all your help I expected that, and am being patient.
I have actually only cried once since it happened, when I was walking back from the car into the house after I left hospital and I was looking down at my stomach, which now looks about 5 months pregnant, and I can see it! I know it always looked like that and I just couldn't see it, but it still made me sad.
I do have a real feeling of a new chapter opening though, feeling like I'll be wanting to exercise more, focus more on dressing stylishly. I've already been eating better, even though I'm stuck in bed.
