or, pulling yourself up by your bootstraps doesn't work if you don't have boots
This is why people’s suggestions about how to relate to depression often strike those of us who suffer it as sententious bullshit. Praying is not going to get me off this ride. Neither is meditation, or drinking wheat grass juice. I cannot change my mind in the middle of the roller coaster track, before the plunge. No one will let me off. Praying, meditation, diet, exercise, therapy, all your suggestions may be useful tools. They may help a person keep breathing until the ride is over, for the time. But they do not eradicate the brain chemistry that makes one prone to depression in the first place.
