Hallie,
Enjoy your success, you've earned it. Don't let people who you thought were your friends bring you down because they're jealous. I agree, your friends looked to be on the heavy side themselves, so I'm sure that they were just jealous that you're not "one of the fatties" anymore and that's a shame. If they were really your friends, they'd be happy and supportive and, most of all, PROUD of your accomplishment. As for your mother, I know she loves you, but please, she should be happy that her daughter is physically in better health than she was having lost 200 pounds and she should be proud of your accomplishment, not make you feel guilty for doing so. If I lost 200 pounds, my mom would take me shopping herself for a new wardrobe, not tell me that I'm bragging. She'd say that I have every reason to brag. That's a HUGE success. I'm glad you and Shannon are not together. Now, you can go out and find someone who appreciates you for the good person you are now that your outside matches your inside person.
Take care and God bless you! And Congratulations on your wonderful success!
