I know what you mean, Debi. Between my family, job, and riding, I had plenty to do, and my first inclination was to throw myself into everything and just try to forget that it ever happened.
But after the trauma of open lung surgery, sitting in chemo rooms with other cancer patients, and interacting online with others who are later lost or lose loved ones, it's easier said than done. I think getting involved, trying to help and give support is therapeutic for the soul.
