Staying Home good or bad what do you think?

I stayed home with my daughter today.I got some house work done. I cooked breakfast and went over some much needed school work with her like her alphabet, numbers, Spanish etc. I loved every moment of it. I feel bad that I can't do this for her every day and because I am the one who makes all of the money and pay all of the bills I can't do this every day. I love to go to work every day but I feel I will love taking care of a family so much more. Especially with my dealing with the every day ups and downs of lupus I feel I miss so much that I will never get back and should I really be putting this much time into someone else's business when my life can end at anytime? I work hard so that I can give her what I never had but will that help if I am not here for her in the end?  What do you think?
