What can i do to cope with the stress that comes with growing up?

Talk with others: Your information indicates you're 45, but we're never too old to grow up! :-) seriously, life transitions and developmental changes are stressful -- but they also open the gates to new adventures. Talking with others who have been through what you're facing can help you see things in a larger perspective; stress can decrease from this and also from feeling less alone with your crisis.
