Thoughtless comments from others during pregnancy...?

I don't know about most of you ladies, but I have been feeling happy about my pregnancy but a little stressed on the weight gain and how to loose it afterwards.You think that people around you would be more understanding and motivational. Though in one day I had 2 comments, one from a good friend and 1 from my mother. One saying " I will never get my body back to how it was" and another saying that "I will have to work out extra hard to be able to loose those extra pounds" These comments just killed my spirits and I got very down and sad.I hadn't given up on my weight loss fight and have already got oraganized a "boot camp" through my gym 2 months after baby is born.. Have you ladies had negative words from people? It was so unexpected that it happened from my two closest people...
