As I've known this far, OCD sufferers might have unpleasant obessions like "I want to kill my father", "I'm afraid that I'm bisexual" and many more.
But there are also other obsessions: "I must wash my hands again, they ain't clean enaugh", "I've not completed this task, I can't move on to other task 'til I've done this or that", "I must put these books in this order, it ain't right the other way".
Now when you think about it, as these obsessions shape your 'needs' and 'wants', would you even accept doing things other way? Although they might interrupt your everyday life, you still get 'pleasure' than 'anxiety' by doing them.
EXAMPLE:
1) You like to do THING1
2) You feel pretty bad and anxious if you do THING2 than THING1.
3) But apart from anxiety you want to do THING2 more than everything, but you can't simply because these obsessions tell you "Do THING1. Don't do THING2" (You want to do THING2, because not doing THING2 would interrupt your everyday life).
4) And you're so damn comfortable doing THING1 and these obsessions have made you to like doing THING1. From now on, as you are able to do THING2, you'd still miss THING1 and you don't even want to change.
[An example for this EXAMPLE would be: Someone would have obsession to listen one song 'til he/she memorizes every single note and lyrics of this song. Although he wants to listen other songs more than everything, he simply just can't yet because of this obsession. And this someone actually likes to listen songs this way. After weeks of listening, he has listened three songs like this and he accpets doing this for years, even if he wants to listen them more frequently. And that person doesn't even want to change, he accpets and likes this way of listening songs, even if deep in his heart he wants to listen hundreds of various artists, albums, but this will be limited only to one or two artists because of this obsession.}
-I know, this is pretty complicated what I just explained, but if you understand it, what's your opinion on this?
