I think the most crippling phobia is Apeirophobia (fear of infinity). Infinity is a mathematical concept, everyone understands the concept of it, but when you actually think of its magnitude, you can easily get overwhelmed.

Just think about touching an object, according to infinity, you will never touch it because the number will just get smaller and smaller into decimals. That’s crazy to think about because infinity makes so much sense but it fights logic.

Thinking of all the infinite possibilities is overwhelming and almost makes you feel melancholy from it complexity which we can’t experience. I don’t have this phobia but I have experienced it overwhelmth and I understand how there is just so much to take in that it is INFINITE.
