Undefined lyrics

I'm not happy though I know I'm not sad
I'm not... please though I can't say that I'm mad
I've got no name for my state of mind
call me undefined
I'm not content though I'm not out of place
I'm homesick though I've been home all day
I've got no reason, reason why
I'm undefined, yeah
it's great, the state I'm in

colorless, no emotions within
how I wish that I knew what was wrong this time
call me undefined
ohhh, undefined
I'm lonely though I'm not alone
she's here with me
though it feels like her heart is gone
how I wish I knew why
I've been so lonely, so lonely tonight
ohhh, I'm undefined
