My sister has OCD. Last year she stopped eating and drinking water. For ten days, she has not eaten anything. We took her to the hospital. The doctor gave her medicine too. For 25 days, she was in the hospital, then she was fine. Medicines like the tablet Flunil 20 mg per day was continued. She had taken medicines for two months and then refused to take them. She is saying she does not have OCD, but she has two souls inside her body. After she stops taking medicine, she takes more time in the toilet and for baths. Doing so much repetitive things. And for the past month, she has got angry with me (I am her brother) because I took her to the hospital last year, and she is blaming me every day at least once, shouting at my family and me. Now I am also afraid of her. I am very much depressed. Please suggest what to do. It will be a great help.
