pinkee, Peanuts, and Louisa - welcome aboard! Glad to see you posting instead of lurking! Posting is where the "action" starts and you begin doing things to improve your health instead of thinking about them. Most powerful quote I ever came across: "Action is the antidote for despair".
There are going to be challenges ... your "lizard brain", your genetics, your family, your culture. On 3FC you will find people who've found ways to overcome them, and their knowledge is free for the taking. Ask, ask, ask, ask - there is always someone who's been where you are and can suggest strategies.
Don't forget, too, to check in with the Maintainers. WHEN you are successful with getting where you want to go, the work truly begins. You'll spend more time maintaining that loss than you will losing it, so take a little time each visit to understand those hurdles now. That way you won't be fighting the yo-yo.
The deck is stacked against your health in many ways, but it's SO worth it to put yourself first and join us on this trip! Get selfish ... YOU DESERVE TO BE FIT, HEALTHY AND HAPPY! Seriously!
