I doubt there was any significant mental illness ensuing from such an offense, certainly none more than what existed prior to that.
Many doctors and therapists aren’t taking insurance anymore, especially since many insurace providers don’t want to cover the cost of therapy (psychopharmacology is much cheaper, and in many cases, is necessary). It is very difficult to get insurance providers to cover psychoanalysis, for instance, which requires many hours, often for the patient’s entire life in order for a breakthrough to occur.
