I have a little bit of O.C.D, but with A.D.H.D to go with it. I don't like putting the periods in acronyms, so from here on out they won't be there.
ADD
First I would like to say that I have never been officially diagnosed with either of these disorders. I do not mean to poke fun at them, just describe me a little bit. When I was a child the counselor at my elementary school told me that I had ADD. ADHD did not quite exist yet. Every child was getting diagnosed with ADD if they couldn't sit in a classroom for 3 hours straight. I didn't want to be put on medication so I avoided it as much as possible. I was brought into the counselor's office to be tested for ADD. I knew what the visit was about before hand so I stopped by the library and did some research on the tests. I studied for two days, the hardest I ever studied for a test. Now, because I have ADD for real, I wasn't able to fully convince the counselor that I was a perfectly normal child, but I did give her enough doubt.
Instead of calling my parents to send me to a therapist, she gave me a note to bring home. I promptly discarded the note in a trash bin on my way back to class. Because she had not heard from my parents after a few days, the counselor determined that because of my ADD I had neglected to remember to give the note to my parents. So this type, as was done with all of the kids who had problems bringing notes home, she taped it to my shirt. I was fully aware that the tape was not permanent, and discarded the second note as well. After that the counselor thought my parents were crazy for not bringing their child to therapy, but my grades were fine and I had passed the test, so she couldn't do anything.
Now, I consider myself a smart person. I think the only reason I have been able to survive this long without medication is because I am fully aware of how my behavior works, and how to deal with it. I was able to make it through high school and graduate with a 4.3 g.p.a. (periods are back) on a 4.0 scale. Honors classes were worth more.
OCD
I have a mathematic, logical, but creative brain. The math and logic side likes things to be in order. I have over time determined that because of this I have OCD. For example, the white board at my office has all of the markers facing in the same direction. My closet at home is ordered by type of clothing and color. The spices in my cabinet at home are arranged by height with all of the labels facing forward. I used to think I do these things for efficiency but I have learned that it is truly OCD.
My friends came to my house to visit one evening. While I was in the restroom relieving myself of multiple bottles of beer, one of my friends thought that it would be funny to play a trick on me. After my trip to the restroom I went to the kitchen.
Friend - I can't believe that you knew right away!
Me - Knew what?
Friend - That I turned the spices backwards.
I quickly opened the cupboard to discover that the spices were all facing forward.
Me - Don't screw with me like that. You know I like things in order.
My friends then related what had happened from their view point. While in the bathroom, they had turned the spices backwards. Upon exiting the bathroom, without realizing what I was doing, I walked to the kitchen, opened the cupboard, and turned the spices forward. The above conversation than began.
The Combo
Now as you may realize somebody with a short attention span that is very easily distracted (ADD Gary) and someone who likes things in order (OCD Gary) don't always have the same points of view. People with extreme OCD will knock on a door three times, then the wall, then the door before unlocking it. I think I have that. But, for me I walk up to the door, and before even knocking the first time, I get distracted by the shiny door handle, unlock it and walk in.
Generally OCD exits at a point where you feel the need to do something otherwise bad things will happen. Sometimes I'll start thinking that this happened because I didn't do that, but then I will get distracted and continue on with my life. Later I'll remember what I forgot to do, and then I'll suddenly start having a panic attack, because forgetting to knock on the door properly before opening it is probably the reason why my computer crashed 15 minutes later.
This combination of OCD and ADD can make me appear fairly normal, until you get to know me. Once I start talking about what goes on in my brain, people have a tendency to get scared. I attribute this to the reason why I always make great first impressions, then... oooh something shiny...
