Stages of my Anger

Recently I've been very angry with some people. And I've observed the various stages of my anger. It is amazing the way I've reacted towards these people. The way I've reacted has varied from complete denial of what they said and did to complete acceptance with some stages in between. So, here are the stages of my anger:

First comes complete denial. I'll try to deny to the core what he/she has said and done. I'll say it's okay, perfectly natural. It doesnt matter. I'll support that person.

Then it hits me, I become angry. How could he/she do this? Didn't he/she think once about me/others before doing this?

Then, I begin to hate that person. Say he/she is heartless, mean, irresponsible, selfish, and arrogant. I dont want to talk to him/her ever again. But, then I'd been such good friends with these people so how could I give them up so easily.

So, i try to talk normally with that person. But, things r not the same again. The way that i perceive them changes, so I can never talk to them the same way.

So, after that i begin to hate myself for ever being friends with these people. I begin to hate myself for not seeing the signs before. For believing all the lies they said and showed.
And, if i reach this stage, then Im done with the friendship. It's over. It is at this stage that I decide whether to carry on or to give up. And, 90% of the times I give up. Somehow I dont think so I can ever forgive someone, if they've hurt me. It is the toughest thing for me. But, thats the way I am.
