I have OCD and while I guess this is funny, it really misrepresents the sheer horror of the disease and reading some of these comments makes me cringe. People confuse OCD with OCPD and think OCD is just having to have everything in order ("OMG I like organizing my room, I must have OCD LOL"). In fact the vast majority of OCD has nothing to do with ordering things. It is a truly life-destroying disorder where you have horrifying anxiety-inducing intrusive thoughts that can only be temporarily reduced by compulsive behaviour (the exact form of the thoughts/behaviours can be nearly anything). The thought process is more like "I have this horrifying fear that my family is going to die of disease that I infect them with if I don't wash my hands one more time. I know that doesn't make sense but there is nothing I can do about it, the fear is so strong. If I wash my hands just one more time I'll be clean and feel better...briefly...(repeat ad infinitum)". OCD is so awful that the suicide rates are much higher for sufferers (I think something like 10% kill themselves if I remember correctly).

TLDR: I have OCD. Most OCD is not being a neat freak. It is truly awful and can be debilitating, and I hope people realize it is at least as serious as depression or other illnesses.

Edit: As pointed out below, the compulsive "behaviour" can just be internal (reassuring thoughts) as well
