Welcome to SparkPeople and congratulations on taking the steps toward a healthier you!! Stress is in all of our lives - it is up to us for how we cope. Here is an article from our resource center that may help - www.sparkpeople.com/resource/wellness_arti
Start small in your changes so that you don't burn out before you truly have a chance to begin. Changing our habits is something we are all capable of...but I think often times we don't forgive ourselves as easily as we would forgive a friend.
Good luck with your journey and keep us posted on your success!!
