If you truly suffer from depression you need to take medication. If not what you are doing is fine. Just don’t call it depression because you are doing a disservice to those of us that truly suffer from this debilitating disease.
The right combination of an SSRI that your body tolerates along with Bupropion or Buspar came make all the difference in the world.
Depression is real and needs treatment.
I hope the people that truly suffer from depression will ignore your post.
Exercise of course will help with any problems but get medical help.
Good luck to everyone on this post.

PS I wish getting rid of depression was as simple as floating around in a pool with a noodle or going on a long walk.
