I can also relate. I was at my highest weight - ever - when I got pregnant and my weight gain has been pretty high. I don't know how high because I'm not looking at the scale when they weigh me, but I know from the rate that I've had to buy larger sized maternity pants.
I feel like a stranger in this new, pudgy body, so I'm trying to keep what little shred of confidence I still have left. I use makeup to help make my puffy face a little more attractive, but at this point, I'm just focusing on my "comeback" after baby.
I'm also setting small goals for myself - such as signing up for Weight Watchers (nursing moms program) by the time I go back to work at 12 weeks. I also want to start walking with baby as soon as I physically can and move onto my old activities of tennis, zumba, and yoga within a few months. Breastfeeding itself should be very helpful, too.
I also like to look at the new moms that I know for inspiration. All of them look amazing, some sooner and some even a year after baby. If they can do it, I can do it.
Stay positive and focus on life after baby :)
