The Working Mom

Hi there...
Its Friday evening and i am still sitting and working. When i should be spending time with my family. Sometimes i get so frustrated with this kind of lifestyle, but i have got so used to it that i can just getup and go. This is one question i ask myself many times, should i leave work and be a stay at home mom? or should i continue working for my identity and financial independence. I know this is one tough question to answer and all working moms think about it a million times a day. But whats the answer nobody knows... :-)
