This may be weird and or of place, but I would suggest taking a look into Taoism. It’s got some interesting ideas that I’ve found can help with depression.
It’s easier to state the ideas of Taoism than it is to follow them, of course, but I think that there’s a lot of truth in the notion that much of our suffering comes from trying to be what we are not. Especially in American society, where a lot of our morality is based upon some inherent rejection of our most essential nature (the notion of original sin is probably the most blatant example of this).
I think that sometimes we get stuck in a rut where we aren’t happy, but we think that we are “supposed to be there, doing that thing”. When in reality, the reason being in that rut makes us unhappy is because, is because it’s not what we really want to do. But we do it because we think we’re supposed to, or because it’s all we’ve known, or because doing something totally new is scary.
Or sometimes I think it even goes beyond that, where we are actually fine in what we are doing, but think that we aren’t… based on some notion that we aren’t supposed to be fine. Like, we’re supposed to make more money, or have more friends, or laugh more, or whatever. But maybe that’s not the case. Maybe that ideal of happiness that society constructs for us isn’t actually happiness at all. Maybe true happiness is just embracing our true nature, and abandoning that external notion of happiness. And in that abandonment, we shed all of the misery that comes from constantly trying to be what we are not.
There is the notion of being “the un-carved block”. Not something which has been altered by others, but just a block of wood or marble which is already perfect and exactly what it was always meant to be. There’s also the notion that it can be anything, and has ultimate potential.
One of the ideals that I struggled with, is how to combine this notion with a desire for self improvement. I do not think that it means we should abandon all notion of self improvement, and just lie around like sloths. But I think improving ourselves is compatible with the idea that or inherent nature is good, if we accept that part of our very nature is to refine ourselves. Our maybe not. I studied it’s different for each person, and that’s kind of the point.
Anyway, I have found such ideas to be comforting to reflect upon, and you may as well.
