question: Hello doctor,I feel like somebody else is there within me. I am feeling like this because some words are coming in mind like somebody is saying within me. These words are horrible and hurt me a lot. And things are being done which I do not want to do in mind without my control. Time after time, problems are increasing.During the starting stage, I heard vulgar words. But after some days other problem which is more horrible. Due to this, I cannot concentrate on my studies. Please tell me what the problem is? Give me a clear idea of the issue. And how to diagnose it? Please help.
