An "Existential Crisis" is when and individual person starts to question their entire existence and questioning if being alive even has a point or if it's all pointless. It also is hard to get out of because when you are debating if reality has a purpose it gets in the way of everyday things, like Making Cereal or Recording Videos or any sort of activity.
Existential Crisis's include the EXITING topics of...:
