Hey Brandi! Congratulations on taking the first step
I see we are in the same weight category, although I have about 20lbs on you
You can find a lot of support groups that can cater to your needs throughout the forum. A couple of us recently started one that does not specifically focus on weight loss, but a healthier lifestyle in general. We believe that if you eat right, control portions, and exercise, then the weight should come off like an added bonus! You can get to that support group by clicking the image in my signature ("Hot & Healthy Challenge Chicks").
It might help to start by decided by which method you want to lose this weight. Will you be joining a diet (like weight watchers, etc), just calorie counting, or etc etc. Once you've got that decided, then it's a good time to sit down and set up some goals. I like to stay away from the goal of "losing x amount of lbs in x amount of time." Reason being is if I don't lose that weight in the specified amount of time, it hurts my ego, and I tend to slip up or completely give up trying. By setting mini goals (like our monthly fitness challenges, or monthly weigh challenges), getting to the finish line can sometimes fly by!
Good luck, and we're happy to have you!
