I struggled with that Arabesque too. It's very very beautiful, but when it comes to playing it just was not "me"...

You said you've been listening to music all day and feel lost- did you not like any of the pieces you listened to at all??
My repertoire is TINY, so I'm not the best person to suggest pieces, BUT I'm *around* the same age as you, and I learned the arabesque sometime last year. So I'm just going to tell you which pieces I've considered learning/ suggestions from my teacher.
I like Ginastera a lot... try listening to his Rondo Sobre Temas Infantiles Argentinos, or one of his Twelve American Preludes. Those are probably some of his shorter and easier pieces, according to my teacher.
I also liked the preludes from Gershwin's Three Preludes, or one of Muczynski's six preludes.
Humoreske by Shchedrin is also a lot of fun, I learned that one. I think it may be quite easy for you (although it wasn't for me, haha).
Bartok's Romanian Folk Dances and his three rondos are fun too.
And I definitely second the Shostakovich preludes and fugues, op 87 and 34- they are really awesome!
