Mentally disturbed. feeling very unhappy

I understand your situation. You seem to be suffering from depressive symptoms including sadness, loneliness, sleepiness and irritability. However information regarding your hunger, energy levels and concentration at whatever you do also would be helpful to decide the severity of your condition. It is easily manageable with appropriate treatment. Some counselling sessions along with medical help also might be useful for you. My clinic is at OMR chennai. I speak tamil as well. 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.
