Why is it...

Why is it SO difficult to care?
I think I care too much... Cuz it's hurting bad... and it's causing me the headache (it's back again!)
Why must I care so much? - it's my nature, can't help it.
Besides, i've put in that tremendous amount of effort - and not seen any result...
I care because I'm responsible... I care because it's against my conscience not to...
Is it possible for me to care less? I guess... if i walk out, i can stop caring... If I don't, I can't.
So how? Walk out again...? Leave again, and make pple think i'm an irresponsible and a super-negative person?
Who's freakin' fault is it lah?
