LOL! I always wondered if I was adopted & my real family was out there somewhere! I can't prove or deny it...
That said, I'm not offended at all. Just sorry I wasn't able to be more helpful. If I had the secret knowledge of accepting myself as is, I'd definitely share it. I'm my own worst critic, but I view the world as my enemy & always expect the worst.
I could come up w/any number of trite sayings at the moment, but none of them will do you any good right now. I don't know how old you are, but from my personal experience, my metabolism has crapped out on me a few years ago (I'm now 35) and I've been completely distraught that I can't do the things I used to (eat fatty food, drink, etc...) without automatically gaining weight. Guess I have to work harder now... and get more inventive. Maybe it's the same for you?
Anyway, hope you have a good night & can be a little more gentle with yourself someday soon...
