dp question....

I have been reading alot of posts lately and find that people will say "well if you're dp...." isn't dp more of a condition you are suffering not neccessarily something you are. This might sound like a stupid question and i dont know if anyone will understand what i mean. so if you recover from dp are you just someone who was dp'd and recovered? i feel like people make it out to be something like for an example diabetes /something you will always have but can control.
