Nope, you turned into a floating sparkling ball.
I think the save is completely hosed. As soon as I load it, Error Trap kicks in and throws up about 12 errors, most of which are pretty serious.
On the good side, I managed to get into edit town and save your sim to the bin, so his money and skills are completely saved. I was able to put him into a new save, with a new town and he's playable.
