No effect can take place without a cause. You do certainly know the cause of your present condition. Given the scenario, when you experience a mental pain, do namasmarana (repeat the Name of God) for a while sitting in a lonely place.  Or sing bhajans (Devotional Songs) loudly in a raised voice. Or if that is not possible, spread the bed and sleep for some time.  Thereafter your worries will disappear and you'll find solutions.  

- Divine Discourse,  Sandeha Nivarini.

Pure Love is a hard solvent for all types of problems. - Baba
