I have OCD.
"So what? A lot of people like having things all neat and tidy."
But that's not all that OCD is.
For the sake of brevity, I will explain one kind that I have. It is known as "Unwanted Thoughts", the name is pretty self explanatory. These thoughts are usually ones of aggression or sexual acts.
A good example of this is someone who has thoughts of doing sexual acts with children. This person's obsessions ['O' in 'OCD']with the thoughts is not wanted and so they will purposefully avoid places with kids, such as a park. The action of avoiding those places turn into a compulsion [the 'C' in 'OCD']. The person themselves would never act on such thoughts but the ideas just pop into their head. It can be very depressing if you don't know what is going on because you seem to be a freak, if you don't mind me putting it that way.
I have thoughts of killing people. I see someone and I see myself killing them. Sometimes it can get very descriptive. My psychology teacher, I was going to slit her throat, left to right, after school on a Thursday. [I am not making this up, I promise]. My ex boyfriend's mom, I was going to strangle her with her own hair then switch our eyeballs because she has long hair and very pretty eyes.
These thoughts come naturally to me and it's scary. I get scared of myself and feel like locking myself up because I am so scared that I am going to act upon these thoughts.
So next time you joke around about OCD, please don't.
