"For a brief moment, they inflict this pain, they feel the release, they may get attention and it makes them actually feel better for a short period of time," former FBI Agent Brad Garret told "Good Morning America."
According to Anytime Fitness owner Pax, nobody close to Storro believed that she could have faked the attack, even when media speculation grew after she pulled out of a schedule appearance on "The Oprah Winfrey Show."
"Obviously [Storro] needs help," said Pax. "And I hope she gets it."
Pax held a fundraiser at his gym last week where he offered a self-defense class at a discounted price to attract more participants. The class, which cost $20 per person, was attended by around 80 people said Pax, garnering more than $800 for Storro's fund.
The money, according to Pax, was turned over to the bank holding on to the account, Riverview Community Bank.
A spokesperson for the bank told ABC News that "quite a buildup of funds had occurred" over the past few weeks. They are still trying to determine how to return the money to donors.
"The account has been frozen until all of this settles down," said bank spokeswoman Phyllis Kreibich. Donations had come in from all over the country, according to the bank.
Storro originally told police that the woman who attacked her had approached her and said, "Hey pretty girl," causing her to turn around. Then the woman threw a cup of liquid in Storro's face.
Storro appeared on "Good Morning America," her head covered in gauze.
"It was like it almost didn't hurt right away because of the panic, you know, like, what just happened, and you're so focused on that, and then once I let it soak in I could start to feel it burning through my flesh," she said from her hospital bed. She said that by sheer luck, she had bought a pair of sunglasses just minutes before, which protected her eyes.
But as days went on, the attention grew. Storro was invited to be a guest on Oprah Winfrey's show, but then news outlets began to report suggestions that police suspected the attack was faked. On Tuesday the Oprah appearance was canceled.
In a post on her Facebook page last week, which has since been removed, Storro wrote that while she had originally wanted to appear on the show to "inspire people and tell them about Jesus," she changed her mind.
"The show was going to possibly turn into another direction, so my family and I decided not to go on," she wrote. "I hope you understand and will still check in on me."
A spokeswoman for Winfrey's show confirmed to ABCNews.com that Storro had canceled her appearance during which she was expected to speak about "her account of being attacked and scarred with acid." No reason for the cancellation was given by the show.
A Vancouver Voice reporter wrote about visiting the park where Storro was allegedly attacked and spoke to witnesses -- homeless people who identified themselves only by their street names -- who said Storro was "clearly alone when she dropped to the ground screaming." ABC News' Lee Ferran and Ned Potter contributed to this report.
