I am BiPolar n have a Panic Disorder. I am in my 40's now, but when I was younger I was physically, mentally and sexually abused. Several months ago, I suffered a horrific panic attack n lost my vision. I was blind for a small amount of time, but now my eyes r still too bad for glasses. I have seen several doctors n no answers. I too, would like to know how long this last. I see a therapist a psychiatrist regularly.
