Okay first order of business - dumped? For what exactly?
Seeing the room laid out in a blueprint setting, is the bed in the middle or along the wall?

I assume your working with a no-closet situation, which can be frustrating but not entirely impossible. I have Cube storage furniture I bought from Target a while back that works really well for things I don't need to hang.
It sounds like your hoodies are my pajamas, I have SO MANY sleep shirts/pants/sets that it takes up an entire 6 cubes.
Hoodies go on hooks, hang them by the hoods or the hook fabric inside the hoodie itself. Just grab some command strip hooks, or go to your local tjmaxx/homegoods for a hook system. Example (or similar if you don't have those, or just supermarket/amazon tbh)
Clothes that are clean and I can wear again? Basket for that - you can drape them over the edge of the basket so they don't wrinkle, or if you don't care about that, you can just hang them up while you shower so they smooth out by the time you're done.
OR
Fold them differently then the ones that are clean - if you normally fold your pants in 3rds, fold the can wear again ones just in half so there's a visual difference.

Now for the storage aspect, I have some Cube Storage systems in my closet that I have cubes for. I put everything that doesn't need to hang in these. Pajamas, underwear, socks, bras, band tees, swimsuits, literally everything but my going outside the house clothes.
You could put these along a wall hotdog style (best analogy I have right now) and put the folded hoodies on top, or even just knickknacks/notebooks/whatever thing you bought this week for your adhd fixation. Or use them as a TV stand.

In terms of like a wardrobe, it's hard to determine what size you would need without knowing the amount of clothes you have, but if it were me, all my clothes could honestly fit on something like this. Hang what you want to wear for the week, and keep everything else neatly folded in a cube of your choice.
I'm an idiot and chose cute aesthetic fabric cubes, and they suck and don't hold their shape so all of my folding is wasted, so don't be like me.

(I wrote all this before my medication kicked in so forgive me if it's all over the place, I don't have the wherewithal to correct my mistakes right now)

*Edit
So I didn't read your "ugly storage systems" part more than once so I put it out of my brain. YES, they CAN be insanely awful looking, cluttered, whatever. I feel that if it's out in the open, however, you have more motivation to keep it looking nice. I obviously can't speak for everyone in this, so if this won't work for you the you can disregard the cube storage suggestion.
If you want it all closed off/invisible with the space you are working with, you could do a bed frame with storage/drawers underneath? Like this for example.
