First, you still need to decide what is meant by the concept of "going crazy." causes (heredity is one of the main factors) and mental overstrain can, as a maximum, lead to the manifestation of an already existing disease. acute psychosis (that is, a time-limited mental disorder caused by external causes), it is quite possible to get it against the background of severe stress on the psyche. PS I am not a psychiatrist. I have been teaching psychiatry for a long time and perhaps my colleagues-psychiatrists (if there are any here) will correct me.
It is quite possible if the nervous system is mobile. If nervous breakdowns occur from prolonged nervous tension and even overstrain, then it may well happen that after several nervous breakdowns you can go crazy. Such things.
Take care of yourself! Drink chamomile and mint tea, rejoice more often!
