Okay, so i had a friend that someday we had a huge discussion about something we both got pissed off and we insulted each other very hard, that happaned a long time ago back in 2009 and since that day i never spoken or seen that person again, we are from diferent citys, i was a bit mad the day that happaned it was just a few months after i got bullyed and tried to commit suicide the pain was recent and i didn't knew how to handle it well like i do nowadays, i never meant to say any of the things i said the things i said were very cruel and offensive. I never have forgotten about that person and the thing i said, i regret having done what i did and i always wanted to appologize for what happaned but i had no way to contact that person.

Today i found that person facebook profile, i thought of trying to make a friend request and talk to the person, but im not sure if i should, it has passed so much time since that day, i really liked that person i should had never had said what i said, i also don't know if the person will accept my request or even let me say what i have to say and also im not even sure of what to say since it envolves the dark part of my life and i don't feel confortable talking about it to anyone and even if i did i can't know what reaction to expect since i don't speak with that person in many years and the person probably hates me.

What should i do? Try to apologize or just let it go?
