Hi Emma,
I know it is hard but unfortunately we have no control over what other people say. Its a life long thing. We tend to make it worse by interpreting what other people say wrongly too. How do you really know that she wasn't meaning 'Is that Emma, gosh she has lost loads of weight!' But because you weren't feeling positive you thought of a negative thing.
It wasn't until I was 25 that I began to believe people were looking at me because they found me attractive not because they thought I was a freak! It was me that thought I was a freak and assumed everybody else did too!
Keep at it Emma, you have what it takes to do this, don't let other peoples comments put you off.
Are you packed for the move? Carrying those boxes will be a good work out!
Sara
