It's part of you now, it's not going to kill you. Just don't go sitting in a white room without distraction just to see if it suddenly dissappear, won't happen. If you got it from medication, try finding out when it happened, if you can fix it. If you got it from birth, you probably don't have the stuff in your brain that everyone has. I'm autistic so I'm sure I got some brainstuff going on.
