Actress Amanda Bynes has been making headlines lately from her arrest for allegedly smoking marijuana in her apartment building’s lobby and throwing a bong out the window to starting Twitter wars with a handful of stars, including Rihanna, Perez Hilton, Jenny McCarthy, Courtney Love and most recently Lance Bass.

USA Today reports that her erratic behavior is causing countless celebrities, primarily former child stars, to voice their concern for the 27-year-old.

Mrs. Doubtfire and Matilda star Mara Wilson, 25, discussed with Katie Couric in an upcoming episode of Couric’s talk show how drastic Bynes’ life has changed since starting out in Hollywood.

“She had so much power; she had so much going on and now she doesn’t have that anymore,” said Wilson.

Wilson also touches on the topic in depth within an essay she wrote for Cracked.com called “7 Reasons Child Stars Go Crazy.” She provides several explanations for the public breakdowns of child stars including lack of parental guidance, getting so used to the love and attention they receive from being in the spotlight but then getting tired of it, being sexually exploited, not being able to rebel, not knowing what else to do instead of acting and not being able to escape their fame. According to Wilson’s essay, Bynes’ behavior is typical since the majority of childhood stars tend to act out in their 20s due to the fact that they have more freedom and missed out on being normal kids.

Jaleel White, who achieved fame playing Steve Urkel on the 1990’s sitcom “Family Matters,” also appeared on the same “Katie” episode as Wilson in which he said Bynes “has no clue the train is not on the tracks right now.” White, who worked with the Bynes on the 2002 film Big Fat Liar, also said, “All I can really do is pray for her.”

Rick Schroeder, best known for playing Ricky Stratton on the 1980’s sitcom “Silver Spoons,” recently spoke about Bynes as well as another troubled star Lindsay Lohan, telling ABC News that his “heart goes out to them.” He goes on to say, “They are in a place right now that is not good. A lot of people around them don’t care about them and want to capitalize on it. I feel bad for them.”

Patty Duke, who won an Oscar award at 16 for her supporting role in the 1962 film The Miracle Worker and has battled mental illness herself, appeared on SiriusXM’s Frank DeCaro Show Wednesday and expressed her disappointment with the lack of help provided to young actresses dealing with possible mental illnesses. “What’s most upsetting to me is that the people or the entities surrounding those young women don’t seem to be able to come to their aid as quickly as they are to come to their bank account,” she told the radio show. “I got to be all the way to 35 before (my mental illness/manic depression) was diagnosed.”

Wonder if any of these celebrities will become Bynes’ next targets on Twitter.
