I added therapy to my health care regimen after I had a heart attack and got really depressed and scared of dying too young.
Then I found I was learning good things about who I am, how to stick up for myself, set boundaries, communicate my needs and concerns effectively, all of which made me happy. I still go to work on those issues, because I feel like there is more to do in some of my relationships. I will stop when I feel really satisfied with how my life is going and that I can handle nearly anything.
