I think my personality didn't change much, though perhaps I became a little more serious...though happy with that too as I felt free to be serious IYKWIM.
I did go through a depressed period though. Not sure whether it was due to the speed of the weight loss. It's possible. I think it was more to do with losing buddies. My oneline buddies, rather than my real life friends

Incredibly lonely and confused. Almost as if I'd be put in another room on my own and was looking in at everyone having fun.
I missed losing weight. I missed not seeing the scales go down and totally overwhelmed at the task I had in front of me with few guidelines as to how I could turn what I had been doing into some sort of 'normal' eating (though obviously had been doing strict healthy eating with a firm structure). I did enjoy the challenge, but it frightened me at times.
I'm surprised how totally obsessed I had been, and was, and probably still am with the whole aspect of dieting, headstuff etc. Would have thought I'd grown out of it by now
My life, interests, everything changed so much, and perhaps the speed of the weight going made it harder to adjust immediately.
Wouldn't have been able to do it any other way though, and certainly have no regrets. Just wish I'd been warned about how much things change when you reach the 'starting' line
