Reiteration:
Meditation can be catastrophic for people with depression.
There is a reason any meditation retreat will reject you if you answer 'yes' to currently going through depression.
Empty your mind, empty your feelings? Ummm.... Well, a depressed person has most of their feelings wiped to begin with, except for a heavy, sick, sinking, feeling.
A depressed person cannot think. You catch yourself just standing and sitting, hunched in one place and the whole day has passed.
Meditation is redundant for a depressed person. On top of that, there's so much stress hormones in the system just crossing the legs, and focusing on your breathing get become a source of distress.
People really have no idea what they're dealing with in depression because everyone assumes they've been through it, because that's what psychologists have always assumed. Then a real depressed person comes their way and they have to come up with a different name for it. Add a chronic, or a clinical, or some such bullshit -- it's the difference between alternative medicine and medicine. One is real, the other fake. One requires an MD, the other does not.
I have been going back to meditation my entire life to see if it will help, and it never does. It's good if you're feeling stable to begin with, but can really loop you out if you're depressed.
You don't get how serious it is. SUICIDE is a constant demon. You get that? Kill yourself kill yourself, evolution's kill switch, for the good of mankind, constantly going through your head is not some to be dismissed. If you say, meh, I can tell a depressed person what I want about what they should try and what might work, you are playing with nuclear fire.
