Remorse and Repent

A few hours ago, i came to my senses realizing that i had done something really bad. I wasn't thinking straight when i made the decision and i now realize that it was a stupid thing to do. I know what is done cannot be undone, but i do really hope that it does not affect everything that there is. Eventhough that it is just a risk and a fool's hope, i would like to try it out and maybe, maybe one day that hope will come true but till then, all that i can do is repent for what i have done and keep on hoping that it will not have such big effect.

Yea, i know i am selfish but everyone in this world is selfish in one way. But the thing i do not understand is why did i take for granted everything that has been given to me. Why did i choose to make that decision earlier today and caused everything to collapse like a set of dominoes.

Human behaviour and thinking is so hard to understand. Even so, there are certain occasions and situations where two people can understand the other.......... why is that so? What does it mean?
