The Invisible Girl: Helaina Hovitz
Helaina Hovitz, now 22 yrs old
As the 10th anniversary of the attacks of September 11th, 2001 approaches, we meet Helaina Hovitz. She was 12 when the attacks happened and she suffered from post-traumatic stress disorder through her teenage years as a result of what she saw that day. Helaina Hovitz is 22 now and her life is still shaped by the long shadow of 9/11.
