Hi Sharon! Welcome to the board. I'm new here too, and I've been looking for a weight loss buddy myself. There are posts after posts of people wanting buddies, but I've yet to find someone to actually e-mail back and forth and really support each other.
You and I have similar stats, which is something I'm looking for in a weight loss buddy! I too am 5'9", and I weigh about 261 (I was at 275 when I started a few weeks ago). I have an ultimate goal of 165, but I'm in no rush. I just want it to happen, and I want it to last this time!
I don't have any children, so I'm not the fat parent at school functions -- I'm the fat teacher!!
If you'd like to be e-mail buddies for support on this journey, let me know and we'll exchange information.
