(RNN) - In a new video diary, Casey Anthony is speaking out for the first time since being found not guilty of killing her young daughter, Caylee Marie Anthony.
"It's just a little surreal how much things have changed since July, and how many things haven't changed," Anthony says.
Anthony sports a look in sharp contrast to the way the nation saw her during that last court appearance. Her shoulder-length brown hair is replaced by a blonde bob
, and her eyes are covered in thick, black-rimmed glasses.
The one-time mom wears a white tank-top as she sits back and discusses life in Florida, where she is currently serving supervised probation for a check fraud conviction.
"But the good thing is that things are starting to look up, and things are starting to change in a good way," an optimistic Anthony says.
The nearly 4 and 1/2 minute, black-and-white video, whose authenticity was confirmed Thursday by NBC News and People magazine, has surfaced six months to the day after a Florida jury acquitted the young mother of her toddler's murder.
Anthony discusses her excitement to have acquired new electronic items, including a computer, which she paid for, a camera, which was a gift, and a phone.
"It's kind of nice finally being able to say that I have some belongings that are mine that I'll be able to take with me after I leave here next year," she says.
Anthony says that while she's just starting to figure out her new computer, she hopes to use it to Skype, keep a video blog, take pictures and ease her loneliness.
The 25-year-old also says that she's adopted a new dog.
"I've adopted, and I love," Anthony says. "And he's as much my dog as any of the other pets I've ever had."
But Anthony makes no mention of her 2-year-old daughter Caylee, whose badly decomposed body was found in a wooded area near the Anthony family home with duct tape covering her mouth.
The video, which Anthony says she recorded independently on Oct. 13, promises to be "the first of many." Despite her unease in front of the camera, Anthony says she looks forward to more video blogs and possibly introducing her dog, whose name and breed are not identified.
"This is kind of scary, because I hate being on camera, but I don't know," she says. "I need to conquer that fear at some point, and this is a good start."
At this point it remains unknown if more videos of Anthony exist.
Anthony faced seven counts - including first-degree murder, aggravated child abuse and aggravated manslaughter - in the June 2008 death of 2-year-old Caylee. A jury of seven women and five men spent less than 11 hours deliberating on the verdict, which was greeted by tears from the embattled 25-year-old.
Had she been convicted of first-degree murder, Anthony could have been sentenced to death.
Prosecutors argued that Anthony suffocated young Caylee with duct tape after using chloroform to induce unconsciousness. Anthony, they said, drove the body around for days before ultimately disposing of it.
Anthony, who chose not to testify on her own behalf, has long maintained her innocence. Her defense attorneys claimed that Caylee mistakenly drowned in the family's swimming pool on June 18, 2008.
The young mother originally told investigators that Caylee had been abducted by her nanny. A nationwide search lasted for months before Caylee's remains were found.
