There are many reasons for headache. Consult your doctor for a general diagnosis.  If required get your eye sight checked with an Opthamologist. If all the above are ruled out then there are probabilities of you having emotional issues for which consulting a Counselling Psychologist would be advisable.

I understand your concern. You seem to be suffering from tension headaches. However more clarity is needed regarding your problem. Information regarding your sleep, hunger, energy levels and concentration at whatever you do would be more helpful to decide 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. 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 also available.
