I don't have any additonal advice to add to the already great advice you've gotten. I just wanted to congratulate you on your weight loss and fitness gains. That's positively fantastic! I'm sorry that you've had to endure some negative reactions to it and hope that you don't let others' reactions change how feel about your accomplishments.
Live with intention. Walk to the edge. Listen hard. Practice wellness. Play with abandon. Laugh. Choose with no regret. Continue to learn. Appreciate your friends. Do what you love. Live as if this is all there is.
