I think in the end we have to learn that it should not be the fat that protects us but our right to say no and to be respected as a person, no matter what we look like.
We must feel like we look good inside, like we are proud of who we are, flaws included. And that comes with self belief.
And that everyone is equal, no one has the right to judge or be allowed too judge others. Because what ever they say to hurt it is coming from their ego and has no reflection on you at all. No one is better or worse than us and that we have every right to look after our own needs.
These are things I learnt and I get enough strength from that to build my self esteem and set boundaries and set my own standards and with that I do not have to hide behind a body I hated. :)
Best wishes
Saffy :)
