This is exactly how my OCD often plays out. I spend a great deal of time trying to anticipate and avoid situations that might trigger strong obsessive-compulsive cycles. When I return to awareness and realize that I've failed to keep watch, I become terrified that something awful has happened in the interim.
When a loved one has heart disease or cancer, families rally around -- they cook, clean, drive their loved ones to doctor's appointments, give pep talks, and much more. But when someone is struggling with depression, anxiety, trauma, or other mental conditions, family members are not sure what to do.
To me, anyone who is too far on one side of the fence -- either wanting to throw a pill at any negative emotion, or wanting to blame medications for all of society's ills -- seems to be missing the point. Instead of taking an extreme view, I strive to take a wise, balanced, and integrative approach.
