I feel like often depression is a culmination of all these symptoms coming together so when it lessens you really start to notice and question things that you never really did before. It gives you a really interested look into life but also can make a lot of things meaningless.

I'm kind of in the same boat as you but I guess I just stop myself from thinking of those sorts of issues? I've kind of given up finding the meaning of life for now (I'll figure it out when I figure it out) and decided to give it my best shot. Unless you believe in reincarnations, we only live one life so I figure I might as well use it as best as I can. I mean, I wouldn't mind if I died but at the same time, it would be nice if it was heroic in some sort of sense so I'll keep looking for my perfect ending and until then try my best? Who knows haha
