You're not the only one
I have 2 main fears:
1. Unwanted attention once I've lost weight, and
2. Having nothing to hide my failures behind once I've lost weight
I'm dealing with the first one by remembering I can become strong and agile once I'm smaller. I'm not sure about the second one, but maybe facing my other problems will be a better idea than hiding them behind being overweight.
Really, I don't know exactly who I'll be once I'm smaller. But I guess I can never know the answer to that, at least I'll be someone I want to be, rather than just being swept along with whatever happens, if that makes sense?
I know it's hard, but try to just focus on right now. This meal, this workout, and if you're not eating or working out, then whatever you're doing right now. It's easier said than done, I know, but I find that it helps to calm the "what if??" anxiety
