Sleeping problem. Of my father death.

I understand how distressful it would be for a girl to lose her father that too at such a young age. You seem to be suffering from depressive symptoms due to grief. However more clarity is needed regarding your problem. Information regarding your hunger, energy levels, interests and concentration at whatever you do would be more helpful 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 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 also available.
