[MusicTlk] Perfect pitch question

[Kathryn]

I have perfect pitch, and I have had it since I have been born. I am also totally blind. The difference though is it has been altered most likely in my brain. This happened in 2014. I know nothing else was altered or including voices. Why do you think this is happening? Would there be anyone you would suggest I go to or resources I should look into to work with this issue? Thank you.
