Mental health. Online therapist for him.

Actually my dad had similar behavior around 4 years ago due to stress he used to run away from home talk strangely and suspect everyone With great difficulty we got him to see a doctor and then he got better He was also taking medicines But now it has started again he is behaving the same way We showed him to a doctor again and they gave him medicines once more But he just stays in panic keeps asking what happened to me what should I do and remains stressed all the time I do not know what to do I told him to try meditation but he just says someone has done black magic on him Maybe it is because he has been in that kind of environment since before that is why he thinks like this We are done with this behavior I am 18 years old so I do not want this environment I am thinking of booking an online therapist for him.
