So today I had a chat for like an hour with a volunteer on a chat where people can anonymously talk about something that's bothering them. Granted, they're trained volunteers and not real professionals, but I figured that it's a start.
She/he said some things about a possible burn-out or depression but that obviously only a doctor can really say something for sure, they were only suggestions. And that sometimes you can make things up/worse in your head, especially with those depression tests online, but that I shouldn't ignore everything either because there's probably 'something' going on. In the end he/she basically said I'm happy to hear you still want to get your diploma and that trying to get through seems like the only solution at this point. Obviously that person can't say "this is what's wrong with you", and they're more like someone who can listen to your story and give some advice. But yeah. I feel like I still didn't really get any further lol.
