I guess it's a fine line between what is a phobia or an obsession. I guess what I have could be listed as a phobia, only it seems to be something more than that from how I've reacted to certain things, etc, which leads me to class it as an obsession.
Sorry, I doubt that will make any sense to you.
Anyway, OCD includes many phobias- to take the steriotypical OCD, when you are scared if you don't wash your hands, that is a phobia, so you therefore overly wash them.
Phobias can be obsessions though.
I think I've confused myself. Lost my train of thought now.
Take care xx
