I know I need to get hangers… maybe? I’ve gotten rid of most of my things (misc computer components, clothes that no longer fit) but I’m 20 years old with the mental age of a 9 yr old. I had to borrow the broom from a roommate. I don’t feel like an adult.
It’s honestly not bad since you don’t have a lot of stuff.
Like you said, some hangers are a priority purchase. Need to do some non permanent runs for the lan cable.
Beyond that, you’ll want something to get the bed off the floor, be it an actual foundation/box spring, or something improvised. It really does change things mentally to have a proper bed. It feels more like a proper home than a temporary cot somewhere. It is harder to move, so if this is going to be a few months stay, it wouldn’t be worth it, but if you’re looking at a year or two, you’ll want to figure something out.
Curtains would be another mid term option. Not worth it for a few months, worth it for a year plus. Makes a huge difference in sleep with the light better limited.
The rest? Depends on house rules. Like someone else said, having more than bare walls makes even a small room feel cozy and homey rather than like you’re shoved in somewhere. You can use poster putty if you aren’t allowed to hang things more securely.
But look, at 20, nobody feels like an adult unless they’re delusional lol. You’re just starting out in that regard, there’s going to be bumps and a lot of changes as you figure out how to get through life. Don’t worry about it, just learn from any mistakes you make so the next mistake is different, and you’ll be fine.
Finding life balance is a thing. It takes time. I can’t honestly say I found mine until my mid twenties, and it still took a few years to figure out how to maintain it through changes like moving or new jobs. You’ll be fine homie :)
