Rearranging the apartment

Hey Cuties

This is a personal post today, cause I want to rearrange my apartment.
The problem is just I don't know how. 

You have to know, I only have 2 rooms and a bathroom. My kitchen is with in the living room, so I can't rearrange that much. I can't rearrange the kitchen and I want to seperate the living room and the kitchen. So I need new furniture. But HOW ( ؕؔʘ̥̥̥̥ ه ؔؕʘ̥̥̥̥ )?
I need some ideas. But I guess I have a idea for that.
For my sleeping room I get a selfmade bed from my father. He said I will never need a new bed lol.
I will show pictures if I'm finish with the rearranging. Maybe I colore my walls too. But in the first place I need more shelves lol.
