Okay, now cheerful one. Listen up: there are two distinct types of memory. One is pure "recall" and that is the type of memory you use when you're a contestant on Jeopardy. You use that kind of memory when someone says "what's the answer to this?" and you use the prefrontal cortex portion of the brain to summon up at will whatever necessary facts/details, etc. on demand. And the prefrontal cortex "shuts down" under extreme conditions.
That is the type of memory that freezes under stress. That is the kind of memory that no matter how much you studied the night before might just FREEZE solid when the teacher calls on you. That type is victimized by anxiety. That is the type you were using when you tried to force yourself to recall the exact location of your whereabouts when you felt like you were losing all memory.
The second type is called "implicit memory" - that is the type you use to remember how to ride a bike. That is the type you use when you're busy driving, talking to someone, or worrying about going insane, that is the type that "knows' the way home. That is the type you have NO control over whatsoever. That is the type that will never fail you.
If you torment yourself by trying to call up facts/details under massive anxiety and then freak out when you're on a three second delay, you will scare yourself more each minute. And while you're freaking out, the other type of memory will be just fine and will be leading you home (even if you cannot recall your address)
Anxiety, my friend. Too much watching of self. Too much fear of utterly unfounded imaginary ideas.
No one "forgets" things because of dp, dr, anxiety or obsessions. We temporarily lose the ability to have fast recall (the same way a normal person might freeze up if someone put a gun to his head and said "tell me the names of all your children." he might literally not be able to recall.)
Remove the gun.
No amount of "practice" will reassure you and you will only keep upsetting yourself.
Peace,
