Amanda Bynes' worried friend Jonathan Jaxson has compared her to tragic Amy Winehouse.Publicist Jonathan Jaxson - who is one of the few friends Amanda keeps in touch with - believes the troubled actress is heading the same way as Amy, who died in 2011 at the age of 27.He told MailOnline: "She's been promising several individuals to record and appear at places, but just can't keep her commitments for whatever reason. She would rather be alone than have friends with her in person. Amanda is not a Lindsay Lohan or Britney Spears, she is taking the steps of both of those combined with Amy Winehouse mixed in. Sadly, it could turn tragic unless she gets well!"Jonathan also revealed Amanda's only companion is a new puppy and says she has completely cut her family out of her life.He said: "She still doesn't surround herself around anyone on a daily basis and is a lonely blue jay."It's really sad. At least she has a dog now to keep her company, that she loves and treats like a newborn baby."[When I call her] Amanda generally makes very small talk. In texts her messages are that of a high school teen who just wants to be loved. You can sense there's pain and loss of control in her personal life when talking to her. She's been leaning on a few enablers, but quickly deletes them from her, life and then moves on."She's definitely not OK. Still more erratic as ever and between the drugs and what ever mental things she maybe is going through, she's only getting worse. From what I know, she's not on medication or even seen a doctor."Her family have attempted to intervene but, last time they did, she fled to Buffalo. Every time they reach out she just gets angrier and angrier. She has alienated everyone."She needs help, but refuses. It's similar to the downfalls I chronicle in my book and what drives one to go so crazy for fame and that addiction that is very hard to kick. Amanda is intelligent and knows half of the time what she is doing and why."
