It seems as though the problem is primarily fear and/or aversion. The mind is kind of like a cavern of echoes, and you can choose to add power to, or dampen, the echoes. Are you able to think of something that will bring up a wholesome feeling, like kindness toward an animal, or a baby, or gratitude toward a mentor? If so, you can use it to dampen the fear pattern.

When the fear pattern arises again, realize as quickly as possible that it has come back. Stop it, i.e., do not walk down a road in imagination related to the fears, imagining painful outcomes or whatever. In other words, gently stop the thought and drop it. Relax tension in the body, especially in the head. Smile. And bring up the wholesome feeling, however is appropriate for you. This dampens the fear echo. Each time you do these steps, you are taking energy away from this habit of your brain. Every time you do it correctly, you're taking a step toward not being bothered by this concern.

This technique will work, but please just try it and try to do it diligently, giving it provisional belief. In the meantime, try to do your assignments, watching for your fear to decrease.
