Congratulations on taking the first steps! It doesn't have to be fast... it just has to be done.

You can do this! We're all trying to be a little healthier and drop weight in the process.
Have a look around, there's the 300+ group area, and Dieting with Obstacles that may appeal to you, also the 100 lb club, a very active group. You may want to start there, but branch out and post wherever you're comfortable.
All the best of success!!!!
