Help!!!!

I thought the walls were closing
Turns out that was only the doors
Of the closet where you the skeleton lies
Freed from the cage
Freed from the hell
Inside the walls of the institution

Even though we don’t understand at this point
That all we need is hope in people,
So hope seems even further away (further away)
All for nothing (nothing at all)
All for no one (no one at all)
These lies are getting tiresome
These lies we've heard before

It’s all falling down
Coz you stand for nothing (you stand for nothing)

It’s all falling down
Coz you stand for nothing (you stand for nothing)

Hung, dead, drawn and quartered
Left, long, alone and cornered

Time, space and to live alone

These walls still close in
These doors still shut
These ghosts of you still haunt me
Like in nightmares where you steal my soul

And I pray I'm not alone with her
For my mind it supersedes the minds of them
To my own devices to me I’m left
I am left
I am left
I am
Left...

who sings this and what's it called? I can't figure it out for the life of me! please help!

Idk...
