Welcome and congrats on taking steps to take charge. You will find a lot of tools here you can use.
My suggestion is to become a regular on threads other than Newcomers...suggestions would be the No More Jiggling in January in the Women's Corner section and the 100+ thread in the Weight Loss Tips section. There is also a Motivational thread in the Women's section you can use for weekly goals.
Following a few key threads often helps you connect in much quicker and get great answers to your questions, as well as support along the way.
Good luck, glad to have you!
