My wife is always running around these days and took off her clothes today. Is this schizophrenia?

She's hurt. Take her to a psychiatrist and find out the cause of her pain.

Even if she is mentally abnormal, it is because she has been stimulated. So sending her directly to a mental hospital to take medicine can't solve the problem, which is the root cause of her illness.

If the psychologist trusts her, she will tell the secret, find the root of the disease, and her illness will be half cured, so there is no need to send her to a mental hospital.
