Mental fatigue. I force i have headache.

Hi, from what you have described, it seems that you are have been under stress for some time now. This is causing you to get tired easily, get distracted leading to concentration issues, lack of focus and irritation. Try to identify what is it that you are worried or stressed about. Try relaxation, yoga or breathing techniques to reduce your stress. Try to look at your problems with a renewed perspective. Look at them as opportunities to excel rather than having a giving up tendency. Once you are able to handle your stress, you will find that you are energetic and enthusiastic about life and things in general. Eat good nutritious food and do physical exercise . Sleep adequately and also hydrate yourself well by drinking water at regular intervals. In case you are not able to identify or get over your stress on your own, do consult a professional, either a Psychiatrist or a Psychologist for counseling. You will definitely feel better. Hope this helps. All the Best!
