How does one deal with extreme bitterness?

If you have seen some of my past questions, you might be able to tell that I have a few issues to deal with. The most severe one would be bitterness.

Just to illustrate how bitter I have become, I should probably explain the events that led to this bitterness. This is going to sound a lot like a pity party. I'm not trying to make you pity me. I'm only trying to offer my point of view so that maybe you can understand my emotions better.

Ever since I was a kid, it has been my dream to join the US military. I studied their ranks, formations, various types of vehicles, uniforms, chain of command, weapons, tactics, you name it. I was obsessed with my research.

For my senior year, I got accepted into a military school. My studies increased, and I became even more passionate to serve.

At the end of the school year, I was contacted by several recruiters, one from each branch, including their reserve and guard components.

Each one of them turned me down for having Tourette's syndrome. At first, I was okay with this.

But slowly, as I got more menial jobs, I started to seethe and hate the military. I would often wish I was in Iraq instead of a kitchen. I invested so much, and got nothing.

Now, not a day goes by that I'm not green with envy and hate. I often ponder ways to plot revenge. I need advice and understanding. Yes, I've said pretty crappy stuff in previous posts, but lately, it's all I know. I just can't get this hate out of my life. Thank you for your help.
