Memory Blackout

My daughter has this on her all time when she has to write a test or an exam and I believe it has to do with stress and anxiety . I am going to take her to the doctors about it to see if there is anything they can do for her for next year because one of my cousins had the same thing happen to her when she was in college and ended up with Alopecia ( this is where your hair falls out due to stress and the more you worry the more you lose your hair ) . Your friend should really have this checked if it happens again just to make sure that is is nothing serious .
