My elder brother has symptoms of psychosis for the past 4 years. We have got him treated through various doctors, he goes through different phases (duration near about month) of mind. Sometimes he talks with me & share his thoughts but he has never been the same (normal) now his condition is bit more serious he has stopped talking to all of us, eats very less. He has a delusion, he thinks he has a bladder problem so go more than 100 times toilet in a day even in night he does not stop. We are very worried about him. Whole family is under sadness due to this problem. Please suggest us what to do? He also deny and resist to get a treatment of psychiatrist. It all started when he has set back to back setback of failing in engineering exam (AIEEE) n later during b. Tech. He has to leave b. Tech due to depression.
