I still feel like that over a year later and it's only now that i've really started to do anything about it, just felt too tired before.
Give yourself a bit of a break, you've had a stressful and upsetting time.. you need time to enjoy your little one. Best to carry on as you are, eating healthily, going for walks.. you will lose it eventually.
By the way - my tummy is the same, I hate it! lol
