I understand your situation. You seem to be suffering from depressive symptoms including loneliness, disturbed sleep etc. Information regarding your hunger, energy levels and concentration at whatever you do would also be more helpful to decide on the severity of your condition. However it is easily manageable with appropriate treatment. Some counselling sessions along with medical help might be useful for you. If based at bangalore then NIMHANS is the best option. 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.
