My therapist told me about the circle of control. Draw a large circle on a piece of paper and a smaller circle inside the large one. Whatever you are worried about define it above the circles. In the large circle are things that are out of your control and the small circle is what is in your control. Example, worried about finding a job. In your control would be things like, resume, searching for a job, networking, etc. Things out of your control, are other peoples play into getting a job, like being called for an interview, or returning an email, or actual hire. The things that are within you control you can worry about (of course, not for long) but the things that are not in your control is off limits to worry about because it serves you no good. When you realize you are stressing about things that are not in your control, you must do everything in your power to redirect your thoughts. I have found this to be very helpful. I hope it helps you
