To be out of stress

This month my wife and I were facing lot of problems and we wanted to come out of it soon. My wife told me to be very cool, but I am not able to be as it is my responsibility to take care of my parents and my children. My wife says not to take decision in a hurry as it will lead to more tension while implementing it. I wish the problem will be resolved soon so that I can be releived from stress soon.
