one of my relatives has unusual behaviour. she speaks to herself, murmurs which others can't hear, she cannot maintain time, spends her time sitting or lying on her bed, she also frequently suffers from depression and a constant headache with a feeling of vomitting and shaking of hands and legs. she is quite suspicious and feels that others will harm her and her parents. There are many more problems she is suffering from. I want to know what is wrong with her. please suggest a solution. Age-23 years, being treated for 5 years but of no use.
