feelings/impluses

Weeks ago, someone told me that I often reacted, responded and made decisions mainly based on my feelings and also my impulses.

I do agree on that statement, but I didn't know it could be this harmful. I've made a seriously harmful decision without using my brain, which its main function is to make rational decision (guess my frontal cortex still haven't fully developed huh~) !

I've created harm, I'm sorry, nothing I do can erase that hurt away just prays that time will heal it, somehow, and I am fully responsible for it... It is a consequences I will have to face anyway. My bad...
Sry... I really know it's hurtful, I really do...
But I promise, from this mistakes, I will have better control over my feelings and impulses!
