Please help me fix my desk set up

I never understood people who freak out about desk setups until I got to med school because something is wrong with my setup and I don't know what it is that I could fix other than scrapping the whole thing. Like I'll just show you. This is her. It's not the most glamorous setup. It doesn't really need to be. I feel like I don't have enough space because you see that guy right there? That is the first day textbook. My beloved. I love her. The problem is is that when I have a video playing, right? I don't keep my keyboard on the desk when I have a video playing. I'll just have the textbook here and I'll be writing. But it's not a ton of space. It definitely is usable. Like I don't absolutely need to go out and buy a new desk. But it's cramped. And so I was thinking, what else could I fix? And so I was thinking maybe the monitor, like the actual mount I could get a smaller one. But then the back is actually weird because it's not the ones you'll find on Amazon where you can like screw them in. It's like a slide up one. And I don't think I should be the type of person messing around with the mounts of my monitor unless, you know, it gets to that. Maybe I could still get a little bit of a lesser stand under it though. But then the other problem is I feel like that corner is really dark now because this lamp is over that and like the height is just weird. It feels like something should be over here. Then I also have like this weird removable desk shelf situation and it made a lot more sense when I had my desk in the corner because like it was all like, you know, snug and like a lovely little nook and cranny. But now, now it's just it's just stressing me out. And I don't know how to fix it.
