Do I really need this?

I live in an apartment. Just the basic needs are fine. But mostly a lot of people who come visit me say I look miserable. I just have a wifi. My work computer. A mattress on the floor, drawer for clothes.on my kitchen its just the rice cooker. A dish rack. An electric stove and thats it..no whatsover decorations. I dont really think I need them. Idk i kinda feel embarassed whenever people come inside my apartment. I kinda like to earn money so i dont buy a lot of stuff.
