Oh my god literally me too. Literally exactly the same situation. I've just given up. I haven't told any of them yet besides the fact I'd had thoughts, but I've done like 3 assignments since September, and I'm sure there's been 10s on 10s. The thing is there's no motivation or concentration and yet when there is, I end up going to do something that I vaguely care for. I've literally given up on the year and it's costing me 10k in the future, because whatever, right?
But yeah, I've still been depressed AF. I feel you completely. You're definitely not alone — a lot of my friends feel the same and actually I know quite a lot of people and that's some form of relief at least.
What you can rely on is the fact that you're not alone. I think we're at the worst stage of our lives in terms of mental health (even though feeling fully developed), we go through a lot of complete social b*llshit and academics are just ridiculous, particularly if you're at college/university.
It's nice to see I'm not the only student here, things are messed up dude. I'd love to just work full time as I do over term breaks, and just wake up, work, go to bed, and have weekends to stew. Imagine the money! I earn above minimum atm, but I have no doubt it's better than this.
Regardless though, I'm giving myself this year to hang out with other students and forgetting the 10k. I like hanging with ppl and doing what I want alone. But can never figure out what to do next year. Good luck
