I agree with Cirandella...don't give up and losin' weight your whole life is nothing but a WONDERFUL challenge. Don't stop and don't ask why you are doing this....just say WOW I am doing darn toot'n great at it.
I saw your "I have been losing weight all my life. What does this say about me?" comment...and you know what? It says that you're persistent! You haven't given up, and you *don't* give up. I see you've lost 17 lbs., too. That's nothing but positive. I'm almost 60, and it's taken me this long to lose my weight, so never give up! All the best to you.
