Depression. Condition becomes severe.

I understand your concern towards your brother. However more clarity is needed regarding his problem to decide on severity of his condition. Don't worry it is not his fault, it is the hormonal and chemical fluctuations in brain as a result of stress which is taking a toll on his mental health. It is easily manageable with appropriate treatment, so that dysfunction due to the same can be reduced and his quality of life will improve. There are options of long acting injections available which would be useful for him. Some counselling sessions along with medical help might be needed. I suggest you take him to a nearby psychiatrist at the earliest. I would also be more than happy to help you with that if you are looking for further online suggestions. Discussions will be held confidential. You can directly consult with me through Practo as needed. Online chat consultation is available.
