It doesn't take much to trigger an existential crisis for some people, just ask them the right question or say aloud their private thoughts of self doubt and watch the crisis unfold upon their face.
If you feel like you're on the verge of having an existentialist meltdown then you should probably refrain from reading the "thought provoking" memes shared by the Instagram account textsfromyourexistentialist.
This suggestion is for your own safety, because any one of these memes could trigger a crisis that will take you months, if not years, of therapy to defuse.
