I understand your concern towards your sister. However more clarity is needed regarding her problem to decide on severity of the condition. It is easily manageable with appropriate treatment, so that dysfunction due to the same can be reduced and her quality of life will improve. Some counselling sessions and if needed medical help might be useful. My clinic is at OMR chennai. I would also be more than happy to help you with that if you are looking for online assistance. Discussions will be held confidential. You can directly consult with me through Practo as needed. Online chat consultation is also available.
