To Stay at home or go to Work

SO Heath has given me the opportunity to stay at home and I can't decide what to do. This is a huge decision for me to make. I have worked my whole life, and can't imagine not getting up every morning and going into work. Soooo staying at home and being a mommy sounds like a great idea, but do I want to give up my adult since of responsibility at a job to stay at home??? Hmmmm
