There isn't a single path out of depression. There are many paths. Unfortunately, they don't all work for all people.
For me, mindfulness was key. I understand that doesn't work for others.
Just like some people like cilantro, and I hate it, just because something works for one person doesn't mean it would work for the next.
If it doesn't work straight away then try some more.
(that's my hope at least, if it doesn't work then at least I die at the end)
Strength is such a wonderful idea. The dao makes a distinction between being strong (external) and having strength (internal).
Somehow containing all your demons and greeting strangers with kindness is an unparalleled feat of strength that no one can witness except you yourself.
Becoming your own witness, detached from the hatred or the euphoria, is the hardest thing about living with depression - but afaict it is the only road available.
