I dont want her to die likee my brother did. please help [/INST] Hello and welcome to Chat Doctor. Thanks for your query. I understand your concern for your sister. From the description of her symptoms, it is possible that she could be suffering from a depressive disorder. The significant loss of weight and the severe motivation / with Chat Doctor.  So, it is important that you take her to a psychiatrist as early as possible for a detailed evaluation and further treatment. It is also not a good idea to take sleeping tablets on her own. She needs a detailed psychological assessment by a psychiatrist in order to diagnose her problems correctly and then only appropriate medication needs to be started. So, please arrange a psychiatric consultation for her at the earliest. Wish you all the best. </s>
