You don't handle depression. That's where everyone fails.

You come up with- and handle anything else - ideas, work, gym - whatever.

The moment you "handle depression" or "fight depression" - you feed it.

You kill it by lack of attention to "depression". You kill it by focusing attention to anything else.

Most effective is helping other people with whatever they need. That's because it de-focuses attention from your own needs and when "you are depressed" - that would be your depression.

Go, find someone who needs help and save someone's day. Or life. It could be person, place, animal or good cause.
