If you don't feel anything, don't pretend that you do. You'll regret it later. It won't give you the 'payoff' you seek later, it would be like having someone else write a letter for you. You have to be the one who writes it.

Remorse is an emotion, like anything else, subject to change at a moments notice. If all you want it to be purged from guilt, then watch porn and eat ice cream to feel better.

Writing a letter shouldn't be about creating a magic spell that will fix everything. Very few things in life are superficial enough to get fixed in one fell swoop. If you really want to fix it, it will take hours, countless words, countless actions, and trying to make it up, by proving you're a better person. From that perspective, it doesn't really matter what you say in THIS letter. It will just be one of a billion things you do to make everything up to this person. You have to *want* to be this person's friend. You have to *want* to give love to them; the kind of love necessary to feel the actual, genuine remorse that you say you feel. Otherwise, you'll be constantly trapped in the ambivalence of just staying friendly enough to not repeat past mistakes.

Do you really want this?
