I am so sick of being so tired all the time. Even the smallest things like going to the shops feel like they take so much effort and leave me exhausted...how on earth am I going to cope with labour?

I mean, coped fine with DD, but that was when I was 10 years younger and a lot fitter. I've been doing a bit of gentle swimming and walking throughout, but as much as I'm getting to the point where I want him out, I don't feel like I'm ready for this...
