Yes, a disturbance in the force!
I finally understood Star Wars after watching the first couple episodes this week with my son.
The dark side of the Force is just a disturbance (destroyer) messing with the force.
Anxiety is just something that messes with real emotions like sadness and pain.
Anakin Skywalker eventually became Darth Vader because he didn't overcome his fear (synonymous with anxiety) and worry about his mother.
He didn't take care of his real emotions, he thought he could avoid regulating and processing his true emotions and remain aloof.
