Algorythms - Screwup

Can I give you all you need
Keep away my selfish greed
Will you let me know when I`m full of shit
And your heart`s about to bleed

Cuz I will try
Even though I know I`ll screw it up
I will try
One more time
When I`m on the top of the world
There ain`t nothing gonna stop my grin
But when I`m down I`ll make you cry
And your tears will make me bleed
Time after time I will say I`m sorry
Time after time I hope you`ll forgive
That you believe me when I pleed
