Like a treadmill

Mama I'm sorry I'm always tired
I'm still searching for a reason
Nirvana is what I desire.
I breathe but haven't felt alive
I walked but haven't made progression
Come home from work and
I don't want to be bothered
Lock myself in and find myself bothered,
I reached out for closure and in return
Only got a cold shoulder.
Why am I always alone!?
All these drugs; there's no longer an effect
All this money but it can't buy happiness.
