Thank you for the replies, everyone, and sorry for my own late reply to your comments. My boyfriend and I broke up a couple of hours after I started this thread (we had been together for 5.5 years) and my world is currently falling apart. Not doing well at all. Life seems even more meaningless now (yesterday I spent probably 20 minutes staring into the wall repeating "nothing matters" out loud).

Anyway, regarding the constant existential crisis:

I don't know about you but I'm a thinker. I spend a lot of time in my head thinking about and analysing things/situations/life. I'm also a person who questions everything and I'm a bit of a cynic and a skeptic. I suspect those personality traits aren't really helpful in this situation. Maybe I/we are not depressed. I don't know, but it's quite discouraging to not see the point in living.

There are a lot more things I'd like to say but I'm not sure how to express my thoughts right now so I'll start with this.
