Hey Scout, and
It's ok to be scattered at first!
One of the best ways to meet people, in my opinion, is through activities...all the better if they are healthy, active activities! What about a walking group, or a spin class? Get out there and you'll meet LOTS of adults...and if you meet them in context of something active, you'll be more likely to STAY active together.
Other than that, just get into the groove of eating better and moving more, and maintain that "don't let my weight hold me back" attitude...it is so important!
Can't wait to hear more from you soon!
