Rage and a possible overreaction

I am a bit . . . scratch that; I am very angry. A bit sad.
How can someone judge me for my very personality? I know me better than you do. I understand my own brokenness more than you ever will, and don't you dare try to tell me how I am supposed to feel or think or react to a situation.
This is a rage post. I may or may not leave it up here, but I had to say something. I hate getting angry. I end up crying in impotent fury, because I can't articulate around sobs. I break pencil lead trying to scratch into paper the strength of my wrath.
Sigh.
There. I think most of it's gone. Fury just leaves behind a lot of hurt, like I got burned by it on its way out.
I may or may not be overreacting . . . but one thing guaranteed to make me incredibly angry is someone saying that an opinion is wrong.
