Might you be suffering a psychological injury
from a traumatic event?
Have events in your past changed the way you see yourself, altered your view of the world, made you more negative, distrustful, insecure, angry or anxious today?
Were you coping well enough for a period, but find that coping is getting more difficult with time? Do you find that coping becomes more difficult at stressful times?
Do you find yourself saying things like, I know that this isn't rational, but.....?
