Fear is always a sign of strain, which arises whenever the will to do conflicts with what you do.
This arises in two ways:
First, you can will to do conflicting things.
This produces conflicted behavior, which is intolerable to yourself because the part of the will that wants to do something else is outraged.
Second, you can behave as you think you should but without entirely willing to do so.
This produces consistent behavior but entails great strain within the self.
In both cases, the will and the behavior are out of accord, resulting in a situation in which you are doing what you do not will.
This arouses a sense of coercion, which usually produces rage.
The rage then invades the mind and projection in the wrong sense is likely to follow.
Depression or anxiety is virtually certain.
