When you are worried, pinpoint exactly what you are worried about, and then try to think of solutions to the real problem.
For example, if you're worried about how to make a living, your anxiety level might be commensurate with someone who's worried that they'll starve to death!
But is that really the case? Most likely, you have the necessary talent to deliver mail, work in a factory, clean floors, or similar jobs. Perhaps such jobs do not enable you to utilize your potential, or you feel they are below your dignity, or will be very boring. So realize then that your real problem is pride or boredom, not starving to death. Your worry level will be decreased if you realize the exact nature of the problem.
Now that your question is how to make a boring job more interesting or how to use your potential, you can make an inventory of all your skills, hobbies, and interests -- and figure out how to best utilize them to earn a living.
