Ok, sounds good that you're feeling better.
Are you willing to admit that you had DP/DR now, then? Because the symptoms you had, and how it slooowly, slooooowly gets better - well, that's in line with the disease. A protective state, a feature of your brain, to shield you from the terror that is your daily life.
Perhaps a better way, than to just remove your posts, is to instead have them edited, yes? With a similar explanation to the one above - people whom then are in a similar state of mind as you were then, will then find your posts, but will SUDDENLY see them in a new light as well - when there's a disclaimer under them, informing them that they need to rethink what they're doing and how their life is currently.
If you recall, around the time you were active, MANY, many others with DP/DR were finding your posts and posting about similar issues - so, there are definitively others out there, who may need the same wisdom you have acquired.
