Hello Friend, Good that you are seeking a help. Appreciate you for  ackowledging the problem and showing interest to solve. Such emotional imbalance is not a big issue. It's just like any other physical illness and can be treated through counseling. Reach out to any psychology counselor locally or you may reach me online for further evaluation.

Feeling low, having crying spells, sleep and appetite disturbances, and difficulty in concentration and attention are some of the signs of Depression. Consult a Psychiatrist for a detailed assessment. It is likely with medication and counseling the symptoms will improve. If you are feeling suicidal or hopeless consult a Psychiatrist immediately.

I understand your distressful situation. You seem to be suffering from depressive symptoms including tiredness, laziness, lack of interest, feeling low etc. However more clarity is needed regarding your problem. Information regarding your hunger, energy levels and concentration at whatever you do would be more helpful to decide on the severity of your condition. Putting up with the feeling that you are unable to do anything is indeed disappointing. Don't worry it is not your fault, it is the hormonal and chemical fluctuations in your brain as a result of stress 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 am a malayali too. 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.
