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!
And now that you don't have to be perfect, you can be good.
