nah, mine didn't either, but it sure didn't help. I'm just prone to depression and have to be careful of not getting sucked into depressive spirals.

but with existence in this absolutely cursed world and childhood trauma instead.

yeah, mood.

one thing that helped me a ton was learning to recognize the first feelings that mean "depressive episode incoming" or "it's about to get a lot worse". for me, it's this sense that I wanted to do something but I didn't feel like doing any of the things that actually came to mind. YMMV

writing is also good. a book is a lot to jump into all at once, but shorter pieces helped me work through a lot of stuff.
