Do figure out what helps improve your mood, maybe even with the help of a t.
(exercise? involvement in an activity? structure?---these are some of the things that many of us have less of as we get older...) And, depression is a real illness, like any other---don't discount the meds, if you try other things without results. All I know is that my mood doesn't change till my behavior changes----and, it took me forever to accept, consider, I do need an antidepressant and anxiolytic to keep my head above water enough to keep on going when I feel that I can't take it anymore.
