Occupied mind is depressing.

[Derryck]

I accidentally offended my friend. I feel sooooooooo bad and until I get her forgiveness I can't think about anything else. Basically I am in physiological hell. Help me... please!

Apologize to her, but you can't expect that she'll forgive you right away.

Like Eduardo said, all you can do is apologise and show her that you're sorry

[charlize2]

When apologizing, tell her how you feel and be honest with her, get it off your chest. It should help you but you'll still need to wait for her forgiveness.

Dude shit happens, try just to be honest with her apologizing and showing respect to her feelings.
