how to solve the problem

Today,I'm not happy and anxious about something, I don't know why exactly! Sometimes I think too much about my life and my job, and it results into a headache. So anyone can tell me how to solve this problem?

Deep breathing exercises can help you to reduce anxiety level to a great extent. I will advise you that from next time whenever you ride on your chain of thoughts, close your eyes and for next two minutes take and focus on slow and deep breaths. Though thinking about your future is not that bad but always remember that anything in an excessive amount is not good for health.

Good Luck!
