Try a little bit of meditation on it. Put on some soothing music. Think of all of the things that bother you at work, allow the anger and frustration to build up, and then throw it away. Do this over and over again until you feel some of the tension start to go away. I know it's hard, but I find this kind of thing really helps. Feel free to join my social group for job seekers if you want. I understand the frustration in not finding the job you're educated for because no one will give you the chance. In the social group, you're welcome to give specifics about what you know you can do, and we'll see if we can come up with some ideas on how to gain that experience. It can't hurt and may be something that could help in the long run.....
