If you want to leave, then just leave. If you want to leave then do not just do something bad just to get banned, that would be very childish and silly.
It is better to leave while in good standing with the WP community, maybe years later you might want to return.

Diagnosed under the DSM5 rules with autism spectrum disorder, under DSM4 psychologist said would have been AS (299.80) but I suspect that I am somewhere between 299.80 and 299.00 (Autism) under DSM4.
