Just wanted to throw my two penneth in - I think you are doing so wonderfully and are a total inspiration. I haven't been in a size 14 since puberty and it is somewhat of the holy grail to me. You must be so proud of yourself. Well done.
I know what you mean about feeling strange though - to me "normal" size clothes look all wrong to me, like dolls clothes or children's clothes, although I long for the day that I can fit into them I think it will take some time until I can stop feeling like someone is going to pat me on the shoulder and gently escort me to the Plus Size range. At least with this diet - i feel like that day may actually come - even though it still feels like it is a long way off.
