WOW! Congrats on the weight loss Amy!! Even after the small gain (after losing 100 lbs it really is small :-) ) you really have accomplished something amazing!!
I strongly suggest relaxing. Don't put so much pressure on yourself! Concentrate on making healthy choices and regular exercise, and it will come together for you. I had someone else tell me the same thing when I was in your shoes. I lost a ton, gained, then learned how to breathe. Now I eat right (almost always
) I exercise (although I detest it lol), and the weight comes off slowly but I see changes in my body every week and you will too! Not to mention the fact that you will have less of a chance of gaining when you take a slow approach. And maybe a little yoga to de-stress and lower those cortisol levels that our female bodies tend to hang on to!
You've come so far already, you can do it!
