Understand depression is in your brain . Do whatever it takes to make you happy , even little bit . Push yourself hard to do little exercise and watch short films funny ones . Talk to people assuming you are perfectly fine . Listen peaceful buddhist music in youtube and talk to yourself that you are powerful and will lead people . Repeat these lines : I am powerful , I am perfectly fine and feel it 20 times . Do again and again and chant mantras in meditation to get relaxed . This phase will go sooner . Hold strong . And still if you are down , know the fact that if you are by chance given some drugs that gives happiness , you will boost up and start loving people yourself and want to live again . So its a game of chemicals - get it done using different techniques .
Still if are not satisfied , talk to experts . The world is big and you must must must must live.
