As you've read, OCD doesn't really go away (at least, as of now, for the general population; some people with advanced or severely resistant OCD have benefited from brain surgery). But that's the bad news. Using the methods you've learned so far, you should be able to keep your OCD manageable indefinitely. So what if it isn't technically “cured”? A little of it will probably always be with you. But it will be more like a picture on the wall than the king of your house.
Hoping the Worst Is Behind You
It's unlikely that you'll go from fearful shut-in to devil-may-care gadabout (although you might: Lucinda Bassett apparently went from severe anxiety sufferer to world traveler, lecturer, and director of a respected anxiety treatment program, so you never know).
