Does anyone know of any guitar songs(without singing) that are really easy to play but really sad and quiet?

I'm not like that good at guitar or really a professional or something lol. If possible, I want the music with no 2 notes playing at once or using over 4 or 5 frets or something like that

U2 - Running to Stand Still
it's very easy to play only has 2 chords.
"D and G" then the bridge is "Am, C and G"
I play that song each time i think of a friend who past away. Drug related. Its a beautiful song to play and to sing.

Check it out, im sure you will like it.

sleepwalk by santo and johnny

Stairway to Heaven. It's long, but do-able.
It has singing, but you dont have too.

You might have better luck with this in the pop/rock section...this is classical.
