My DD is two and I am still not back to pre-pregnancy weight, but even more than the weight, my body shape has changed. My pelvis was injured during labour, I think, as I have had on-going pain that keeps me from being as active as I was before or even during the pregnancy. Along with that, we moved house and my former lifestyle (I walked everywhere) is no longer feasible. I run around after DD and I breastfed (still do one BF a day) and I no longer drink nearly as much as I used to, as I never go out! I eat healthy food at meals, but I do eat chocolate and drink too many lattes. I was never a skinny, exercising person, but my daily activity and an occasional tweak of my diet kept me in a size 10 or 12, which was good enough for me.
Now I feel fat and inactive, and my hips hurt all the time (yes, I have been repeatedly to the dr). I am not happy about it, but people nagging me about it would make me downright miserable, and no, it would not motivate me in the slightest. I understand how you feel, I think, OP.
Forget about making time to exercise for a minute, and think about ways to get more time to yourself, period. I think that's a bigger issue, and its one I can relate to. If you had more time to yourself, you might feel happier and that should come before the weight loss, not as a result of. That's my theory, anyway!
