How can I tell if I have OCD?
There is a difference between a neat person and a person with OCD (obsessive-compulsive disorder).
A neat person knows there is no one who can clean their home better than they can. They love polishing furniture, are pedantic and get seriously offended at family members who scatter their belongings all over the house.
A person with OCD cleans something repetitively (compulsion), as a mean to get rid of involuntary thoughts that they're having. These obsessions can sometimes be very strange.
How to spot for OCD?
A distinctive feature of OCD is the fact that they seem strange for their surroundings, while a sick person sees meaning in them. For example, if a person often keeps order on the shelf where they keep grains, they're simply afraid of insects. But if when cleaning those shelves, they put the jars in a strict order according to their color, shape, etc., it could be a symptom of the disease.
