(CNN) -- Hannah Anderson did what any teenage girl would do after a life-changing ordeal: she discussed it with peers online.
The 16-year-old reportedly fielded anonymous questions on ask.fm website, where she shared details about her abduction by the man she knew as uncle Jim, James DiMaggio.
She did not want to go with him, and did not escape after she was abducted out of fear he would kill her, she said in the postings.
Dawn MacNabb, whose son is one of her closest friends, confirmed to the Associated Press that the postings on ask.fm were by Hannah. She said her son spoke on the phone with Hannah on Tuesday and urged her to delete some of the postings.
CNN could not independently verify whether the postings were hers. The San Diego Police Department said it is aware of the postings, but declined to confirm whether they were from her.
The California teenager was rescued Saturday after family friend DiMaggio held her hostage for a week after killing her mother and brother. Her frantic search stretched from southern California to the Idaho wilderness, where she was found at a campsite by a mountain lake.
'He was my dad's best friend'
During the session, one user asked her if she wanted to go with DiMaggio.
"No, not at all," she said.
Why didn't you run?
"He would have killed me," she said.
Why didn't you tell your parents he creeped you out?
"In part, he was my dad's best friend and I didn't want to ruin anything between them," she said.
Tied up in a garage
Hannah shed new light on the night she was kidnapped -- the same night her mother and younger brother were killed and their bodies burned in DiMaggio's house.
"How did he separate you from your mom and brother?" a user asked.
She said he tied them up in the garage.
"How did he keep the fire a secret?"
Her response: "He had it set where it would catch on fire at a certain time."
DiMaggio threatened to kill her if she fled and brought her at least in part, to help carry equipment in the wilderness, she said.
'Glad he's dead'
Some questions were brutally blunt.
"Did he rape you?
Hannah declined to answer that question.
"I'm not allowed to talk about it, so don't ask questions about it, thank you," she said.
Are you glad he's dead?
"Absolutely," she said.
Psychotherapist: 'In a numb state'
Some experts questioned the wisdom of the online chats.
"This is a 16-year-old who's totally traumatized, she's in a state of trauma and so she's not thinking," psychotherapist Wendy Walsh said. "Sometimes in a numb state, you do things that you don't really consider the consequences."
The teen even posted a selfie ... a self portrait of one's face posted online. She also engaged in lighter conversation, but even some of that seemed painful.
What design did you get on your nails?
"Pink for my mom and blue for Ethan," she said. Her 8-year-old brother was killed by DiMaggio and his house set on fire.
Hannah, who lives in the San Diego area, went missing after cheerleading practice on August 3. The next day, the bodies of her mother, Christina Anderson, 42, and 8-year-old brother, Ethan, were found about 45 miles east of San Diego, in DiMaggio's burned house in Boulevard. The body of a dog was also recovered, police said.
Her ordeal came to an end after a tip from horseback riders sent FBI agents swarming to a camping spot outside Cascade, Idaho.
DiMaggio, the man investigators had sought in her disappearance, was shot in a confrontation with an FBI tactical agent.
When asked what she would say to Ethan and her mother if she got a chance, her response was a reminder of her trauma.
"I wish I could go back in time and risk my life to try and save theirs," she said. " I will never forgive myself for not trying harder to save them."
Those who know her say she spent some of her day helping to plan their funerals.
