Hiya... sorry you are in pain here but you are so very close to being back on top of this situation.

Go back to what worked for you and to get to goal then try maintence. Maintenance for each plan is different - not sure how you got so skinny??? Or you can CAD for your Maintenance or you can do what Curves does, when you get up 3 lbs - induction until back to goal weight.

It will be a constant struggle for you, for us, but I know you can do it. You just need to be aware of yourself, your weight, and your options.
