Is there a medical reason for getting very angry hurting yourself and trashing your soroundings and saying things you don't mean then not really remembering every detail?

Answer 1

Some of the above things you named are symptoms of Tourettes.

Answer 2

Episodes of extreme anger, self-harm, and memory gaps could potentially be signs of a psychiatric condition such as borderline personality disorder or intermittent explosive disorder. It's important to seek help from a mental health professional for a proper assessment and to discuss treatment options. Therapy, medication, and other interventions can help manage these symptoms.
