serious post time but your adviser is an idiot
you're already feeling helpless, so they give you this dumb suggestion of "finding a faith" - which is essentially going to make you feel more helpless because actually, choosing a religion is a momentous decision and not something you should do lightly
blindly following a faith because you think it will give you direction in life is a terrible idea
work on yourself first. worship at the temple of you. it is bullshit and a crutch of the religious to believe you need faith in order to validate your existence.
i am happy atheist and do not need to believe in a moongod to find validity and purpose in life, and you shouldnt feel forced to either
