if you appreciate serious/ dark cinema or reality based movies, do watch "bol" movie. It is a Pakistani movie and a brilliant piece of art showing the gory reality of society.

Be always surrounded by people who love you unconditionally and want to see you happy....like your parents, siblings, any close cousin or best friend, always talk to them about what and how are you feeling and keep letting out your fears, anxiety and doubts. They might not have an answer or solution to that but by continuously venting out your  stress, you will feel relived. Moreover, as a tested remedy, whenever you are stressed, go stand in the shower for a few minutes (mind you hot shower if it is winters ) , this would also help.
