I can't filter sounds. I hear everything and every sound is as important as every other sound. It's a profoundly disabling situation and, frankly, puts a real strain on one's sanity. My problem is not caused by anxiety (not that I don't suffer from that now too). I've been this way since the moment I woke up because of damage to my parietal lobe.
It is concerning that you've started to exhibit these sorts of symptoms. I hope Mark is right and this is a product of anxiety. However, with you insisting on bouncing your bruised brain around (read some of Mark's earlier posts on exercise to get an idea of how much force you're subjecting yourself to) to play basketball, you may have aggravated or even added to your existing damage.
Sorry to be so blunt, but you are putting yourself at enormous risk.
Please Take Care
