Loosing confidential nature. Help me!

I understand your distressful situation and am sorry about your brother's mental health. You seem to be suffering from anxiety symptoms including tremulousness of hands. However more clarity is needed regarding your problem to decide on the severity of your condition. Don't worry it is not your fault, it is the hormonal and chemical fluctuations in your brain as a result of stress which is taking a toll on your mental health. It is easily manageable with appropriate treatment, so that dysfunction due to the same can be reduced and your quality of life will improve. Some counselling sessions and if needed medical help might be useful for you. 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 available.
