Your mind would be always pre-occupied with many things, mostly of worrying nature. This attribute of this could be there with you for pretty long time in your life, sometimes for no reason.

You need to divert your thoughts deliberately away and focus on things which keep you calm and cool. You should start meditation in early mornings, if possible under the guidance of a mentor.

You can also wear a Cat's Eye gem, also called लहसनिया in Hindi. Keep yourself physically fit and healthier.

Best Wishes.
