Which action is characterized of mental illness 1.brushing teeth every hour because ones mouth feels dirty ? 2. forgetting to eat breakfast on a busy day? 3.crying three days over a relationship breakup? 4.feeling embarrassed about going to school after failing in front of friends?

the first one!  :)

Option A

Explanation:

Brushing the teeth every hour because one feels dirty is a mental disorder because practically it is not possible that the mouth gets dirty every hour.

Even if someone has a habit of eating, no one brushes the teeth every hour. I is a type of mental disorder in which the person feels that his mouth is dirty and brushes again and again throughout the day.

Rest of the other options are normal and they are normal reaction of the person based on the situation in which they are placed.

my biggest life lesson is that if you do something bad/wrong it comes straight back to you karma. one time this kid threw an snowball at me then he slipped on ice now that's karma.
