Hi doctor. My boyfriend is facing a problem. He gets depressed. He shouts on everyone for everything. He very confused about anything he wants and everything he is doing. He used say he gets a dream of people following him trying to kill him. He wakes up suddenly with dysnea and sweating. He used to smoke marijuana for about four years everyday more than thrice. Than later he stopped but smokes once in a while. He gets frequent headaches. He feels tired very easily. He stopped mingling with people. He became very cranky. Just wants what he want. Or he will start shouting. Doesn't just think about anything els than himself. What can I do? This is becoming serious day by day. Should I take him to a psychiatrist? Is all this because of Marijuana?
