I've been wondering about the same thing lately. I think you need to work towards getting that hatred out of your system in a way that doesn't hurt you or others.

Has anyone ever validated your hatred? Have you ever been able to tell anyone what the other person has done for you to hate them? I think that with me, at least, one of the reasons I weren't able to start releasing my hatred for a long time was that I didn't really want to - because no one had 'seen' me with it. I kept looking for validation - someone to hear me tell them why I was angry, and react with 'Indeed, what they did was wrong - I'd be angry, too if I were in your shoes!'

After you're 'allowed to have' that anger, once you own it, then I think it's 'just' about releasing the energy from your body - I believe emotions are energy that is supposed to flow freely and finally exit our bodies. But as I said, in a way that doesn't hurt anyone. You could write about it, vent to a person you trust, release it through exercise.. whichever way feels best and most natural to you.

I applaud you for wanting to deal with feeling so bad at the moment
