Well, to try and look at the bright side of things...I don't know how it works in the UK, but I had a friend here (USA) who was your height and she qualified to get to park in the handicapped spaces. I know...this probably serves as very little consolation at this particular moment.
I'm very surprised that no doctors have managed to catch that height error sooner.
Really though, as Marineswife pointed out, you have lost a lot of weight. Just focus on what you've accomplished. Depending on your build, you may end up being perfectly happy with how you look at your original goal weight.
This may not be funny yet, but I couldn't help copy/pasting a joke that was posted in the general chatter forum, under lighten up; it's totally your story.
{I went to the doctor for my yearly physical. The nurse starts with
certain
basics.
How much do you weigh?" she asks.
"115," I say.
The nurse puts me on the scale. It turns out my weight is 140.
The nurse asks, "Your height?"
"5 foot 8," I say.
The nurse checks and sees that I only measure 5' 5".
She then takes my blood pressure and tells me it is very high.
"Of course it's high!" I scream, "When I came in here I was tall and
skinny!
Now I'm short and fat!"
She put me on prozac.}
Really, please try not to let this news get you down. I wish there was some immediate way to cheer you up.
Maybe shoe shopping for some hot high heeled shoes can help a little.
