Just moved out recently too. It did wonders to my mental health. I'm alone most of the time, but I don't feel lonely, and I can visit family and friends exactly as much as I feel like, instead of seeing them all the time.
I spent a bit too much money on furniture, when I could've been just as happy with cheaper used furniture. Can also buy kitchenware over time on sale, instead of everything right away. I agree with >>9576
Take your time, every little piece you add makes your home feel more and more homey. For me a cheap Ikea plant was what I needed to get that warm homey feeling.
I can definitely recommend getting a plunger early on too (I didn't…).
