I think you will find lots of inspiration here. There are several women in the same boat, too much to do, but still needing a little time to focus on yourself.
Just logging your food and understanding where your strengths and weaknesses are will go a long way towards building a healthier lifestyle. Even if you do not have the hours to dedicate to exercise, you can always make little changes that add up like taking the stairs instead of the elevator, parking at the back of the parking lot and walking, instead of a coffee break at work go for a walk outside. You get the idea.
Check out the womens' corner, lots great ladies and lots of great support.
