What a mistake

I said my feelings ache, because i'm a monster;
Sweet petal easily printed, folded, with livid care;
The attention was shrinking and now i regret,
throw your passions like a heavy stone,
no one can catch with no preparation;
The dry lips, when the peek stick into the wearing black,
the stomach convulses and you remember your mistake;
Pain, lose the key of your senses,
because you're disgracing others before corroding you in shame.

(it goes with the idea of giving hope, but in fact being empty and helpless, feeling regrets by imposing even the nice emotions)
