Delusional Tuber diagnosis. Check for symptoms.

The Youtuber expresses an idea or belief with unusual persistence or force.

That idea appears to exert an undue influence on his or her life, and the way of life is often altered to an inexplicable extent.

Despite his profound conviction, there is often a quality of secretiveness or suspicion when the patient is questioned about it.

The Youtuber tends to be humorless and oversensitive, especially about the belief.

An attempt to contradict the belief is likely to arouse an inappropriately strong emotional reaction, often with irritability and hostility.

The belief is, at the least, unlikely.

The Youtuber is emotionally over-invested in the idea and it overwhelms other elements of his psyche (psychology).

The delusion, if acted out, often leads to behaviors which are abnormal and/or out of character, although perhaps understandable in the light of the delusional beliefs.
