High Volume Anger

I am currently experiencing the kind of angry that I experience when I am at the tipping point or the verge of a melt down. I now know how people feel before they go on a fucking killing spree. In life its okay to be an asshole as long as you don't break any laws. If you break morality laws it doesn't matter unless the people above you are moral or have visibility of your moral issues. I swear if there was any power I wish I could have, I wish it was the power of death. I wish I was the cosmic being death. I wish I could only be seen when I want to reveal myself and take the lives of people who deserve it.
Where is a fucking hell girl when you need one.
I am trying so hard to calm down right now which is why I am writing down how I feel so that I don't start screaming or yelling at anyone. I am at the breaking point and it is very difficult to not turn. I have dealt with the billing bitch from hell today, admittedly my fault that I got fucked on this and I was passed up today on going to a lunch meeting with one of our potential hires. My asshole boss excluded me from an interview and picked one of the people under me in stead. Said he had more technical knowledge. I am heavily insulted.
So I have been on edge all morning already and it doesn't help that I owe 110 dollars now that I didn't plan on.
