I just realized i have always had APD

Yeah! APD!! Don't know what that is? You should have met the past me from 5 minutes before I started writing this post and then we would have been like birds of a feather..

     Ahem! (drumroll....) APD is Auditory Processing Disorder. A condition where a persons brain and ears do not coordinate well enough and do not process information the same way everybody else does.
       This pertains mostly to speech processing, for example, you just said something, and an otherwise fairly intelligent(or not) kid/person looks at you like you just spoke an alien language, and you repeat it and he still does not get it.You think, he/she is messing with you, then you ask yourself why is he so dumb, why can he not follow simple instructions? Or maybe you ask something, and the person just gives you a stupid smile like you cracked a joke, and you understand he did not get your question. Or you do not realize the person did not get what you said, so while he is trying to understand what you just said, you keep talking and he is stuck with this soundbite which did not make any sense to him whatsoever and so he discards it in his mind. This happens over and over.

         Or maybe its you, you cannot understand all the dialogues in the movie because they are so jumbled up, or maybe the lyrics of a song sound like a different language. That right there is APD. 

           And sadly, for anyone who has APD, it is a constant mental exercise to go over the sound byte they just heard, turn it this way and that, try to understand it in context, and respond back in the time that is socially acceptable. If this all sounds tough, it is, and its very taxing. There is no medication for this, no therapy. But there is one thing that will help, rephrasing the question.
