I'm sorry, but just liking numbers divisible by 5 or that are even, common numbers is not OCD. Wanting symmetry is not OCD. Being a perfectionist a lot is not OCD. Yes, they are signs of it, but unless you have been diagnosed by it it's just our human brain wanting a pattern and symmetry. It's normal. So stop pretending you have a disorder.
If your doctor diagnosed you with OCD, ignore this.
