omg...I'm so sorry that happened to you. That really sucks.
I can't say this is happened to me. But I know the feeling. Even though I've lost weight, some people don't even notice and it sucks. Granted, these people I don't see often. But it's dissapointing when I'm all excited and no one notices.
Congrats on your 13 pound loss! That is wonderful! I know it and you do too. Don't let ignorant comments like that get you down...well not for too long. (We all get mad and hurt sometimes). You just stay proud of what you've done! Baby, husband, and those great 13 pounds...soon to be more I know!
