The discussion with ocd is always something like that:
OCD: What if this apple is rotten?
me: But I've cut it open and checked, i think it's okay
OCD: But what if it is?
me: But the color seems okay?
OCD: But what if this color is not okay but you think it is?
me:Here, I've googled it, it's okay
OCD: But look at this small patch, it's more creme than the rest of it, what if you just didn't find the specific explanation for it and it's actually rotten?
me:But I'm sure it's not that serious....right?
OCD: Wrong! It's very serious, you're just stupid and can't see it. Let me show another 10000 reasons why it's not like the normal apple you found on the internet to compare it with.
