I understand your situation. You seem to be suffering from depressive symptoms. Information regarding your sleep, hunger, energy levels and concentration at whatever you do would be more helpful to decide on the severity of your condition. Your thyroid levels need to be assessed as well. However death is not the solution for anything. Depression 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. You can directly consult with me through Practo as needed. Online chat consultation is available.
