I want to tell you
Yell it out to the sky
Shout for all to hear
And ask you why
^
Love the start stanza
You wanting everyone to hear and ask him why.
Love the use of words short and powerful! And straight to the point
I want to cry to you
Confess everything I hid
To turn back the time
Undo do everything I did
^
Second stanza
Your expresing how long you've hid your crys and finally want to confess everything. The last line I think remove the "do" because you already said undo it will flow better.
