I understand your situation. You seem to be suffering from depressive symptoms including feeling sad and difficulty in concentration. Information regarding your sleep, hunger and energy levels would be more helpful to decide the severity of your condition. However suicide is not the solution for anything. Your problem is easily manageable with appropriate treatment. Some counselling sessions along with 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. My clinic is at OMR chennai. Discussions will be held confidential. You can directly consult with me through Practo as needed. Online chat consultation is also available.
