Do you constantly feeling guilty as a full time working mother?

I was a full time working mom during my no.1. Yes, I feel guilty for not spending enough time with her. Everyday she will cry before I go working and wait for me at the gate to return home in the evening. After I delivered my no.2, I quit my job and become a full time stay at home mom. But there is another list of guilt e.g. financial burden placed on husband, can't afford to send kids to enrichment classes and not able to coach kids at home as most of the time quite occupied by housework and cookings. There is always a compromise no matter what decision you have made in your life. One thing important is do not regret on the decision you have made.
