Wow! You've done so well already!
I can relate to the comments that people have been saying, both from my own experience and that of my husband when he was losing weight. Maybe you can just tell people that you're living it up in your new healthy lifestyle! After all, if this is now a lifestyle, then this is the new you! They'll get used to it eventually.
As you get to your goal weight, I'd encourage you to consider joining SparkPeople's At Goal and Maintaining SparkTeam. It's a really active team and there are challenges which you might find motivational.
Take care and congrats!
