The most illuminating description of depression I ever heard was from one depressive who postulated that ten feet away there is a table with a big red button. And if you go push that button, your depression will go away and never return.
But he wouldn't walk over and push it; "it's just too much trouble."
I have more trouble with anxiety than with depression, but I've been on antidepressants before and hated every one of them. I exercise; gyms are not closed here in Vietnam because COVID is under control. That helps me more than anything.
This last year has been the worst of my life, but not because of the pandemic.
