Actress Amanda Bynes' increasingly erratic behavior has concerned onlookers pleading for someone to help her.

A friend grew so concerned this week that he asked police to check on Bynes. In an interview with ABC News, Jonathan Jaxson, a Hollywood publicist and the actress' friend, said he got worried after talking to Bynes.

"She started ranting and she was drunk out of her mind. She said, 'I don't want to live anymore,'" Jaxson said.

Jaxson, who was 1,500 miles away from the New York-based Bynes, tweeted his concern and asked New York City police to check on his friend. Bynes has displayed months of apparently bizarre behavior, including tweeting a topless photo of herself earlier this week.

Bynes, a former child star whose recent movie hits include "Hairspray" and "Easy A," this week also tweeted an image of herself wearing just a bra and what appeared to be pantyhose.

"About to put on makeup!" she wrote in a tweet to her more than 896,000 followers. "I weigh 135, I've gained weight! I need to be 100 lbs!"

Last month the 27-year-old tweeted photos of her partially shaved head. She also took to Twitter to denounce media reports she claims are inaccurate.

Bynes' behavior has prompted concerns about her physical and mental wellbeing. Following Jaxson's tweet, actress Jenny McCarthy tweeted "police are at Amanda Bynes house. I hope they get her help. Enough of this circus." That prompted Bynes to lash out at McCarthy, too.

"You're ugly! Police weren't at my house, old lady! Shut the f*** up!" Bynes tweeted Thursday in response to McCarthy, her former "What I Like About You" co-star.

Bynes has since apologized to McCarthy and deleted the angry tweets she wrote. In a November article in Us Weekly magazine, McCarthy described Bynes as "unreachable."

"My heart feels for whatever she is going through and I love her dearly," McCarthy told the magazine.

McCarthy is not the only one who's worried about Bynes.

"Every photo she posts she's alone!! I can't take it. I want to cry," "Real Housewives of Beverly Hills" star Kyle Richards tweeted about Bynes.

As far back as November, another of Bynes' former "What I Like About You" co-stars, Jennie Garth, described her as "unreachable."

"My heart feels for whatever she is going through and I love her dearly," Garth told Us Weekly magazine.

Howard Bragman, a public relations expert and ABC News consultant, addressed the concerns expressed for Bynes.

"We know how things like this can end up, and nobody wants to be the one who says I should have done something," he said. "It's clear something needs to be done, and she's a part of this community. "
