it's all over

I give my all
my all for nothing
and I still have to hear complaints of who is never satisfied!
So why do I keep giving if people, instead of feeling thankful, complain that I haven't done more...more than what I could do without going beyond my limits...
why can't they understand?
It only makes me tired. Those things really make you think of what and who is worthy...
and dude, it really hurts.
