Whenever I read this lines from Kaine, it makes me want to cry in agreement.

This dream is just like death
When I wake up, I am born again.
I rise from death to be dragged through sin each day.
Each day, when I should be happy I act this way…
When I should be sad, I act this way…
When will this day be able to end?

To me, this dream is “death”.
I die every night, only to resurrect in the morning.
I’m so tired.
Am I alive?
Or Am I dead?

This dream is just like death,
When I wake up, I am born again.
When will this day be able to end?
Suffocating in a firey red flower,
Trapped in a body bag and burnt as if I’m garbage!
Is it living which I’m tired of?
Or is it dying?
