New but old (but new but old)

Hi...been here before, but, as usual, didn't keep up with anything. This time around, I'm back (and probably back for good - I hope) I've got newfound reasons and all that and this time I'm not going to fail! So, hello all!! Don't really know how to introduce myself...Um...so here are some basics. I'm 29 and would love to lose a big lot of this weight until the day I turn 30. I live in London, UK...I work in the theatre industry...and I honestly don't know whatelse to say. So ask questions if you want. Cheers, folks!
