Two of my kids had this. One 'grew' out of it. He just had maturation issues with it. My other child had an unusual form of it where her left ear was dominant. Her raw data on her processing indicated she probably used the right side of her brain in language. Even now when you talk to her, there is a slight 'lag' time and she is highly dependent on being close by or picking up non-verbal cues. It is a lot better than it used to be but her scores and processing will never be normal.
Did you have trouble learning to read? Not all people with auditory processing do but some can. It's the sound/symbol and symbol/sound that can really get them.
What is your dominant hand?
I almost forgot, there is a program called Fast Forward that was really pushed to helping kids with this disorder. I never used it for mine (it was costly) but I did use a program called Earobics that worked well for them. An audiologist can test you but you might have to see one at a children's hospital.
