You've made a good start just coming here and posting. There is a lot of support here. Start reading through all the threads and groups and you'll find lots of inspiration and tips on how to get going and keep going. You may not think you're ready to read Success Stories, but please do. The inspiration there is great.
Just remember, start slowly! Don't try to jump in with both feet and change everything all at once. That was my mistake all my life with trying to lose weight. When I finally stepped back, and started small, things started to move in the right direction!

You can do this!
