( CNN ) -- On the outside , kidnapping survivor Hannah Anderson seems to be , in the words of a friend , `` doing great . '' She seems her usual bubbly self , friends say , the Hannah who puts others before herself . But there are hints , they say , of the trauma the 16-year-old California girl suffered when , according to authorities , family friend James DiMaggio killed her mother and 8-year-old brother and kidnapped her . `` She 's , like , acting strong for everyone and I think that 's more of just , like , for her appearance , friend Alyssa Haugum said on CNN 's `` New Day '' on Friday . `` But I can tell that there 's something inside of her that 's upset , '' Haugum said . `` Like when we 're all , like , having a good time and once everyone stops laughing she gets kind of this serious look on her face . '' Hannah endured what would seem for most people an unspeakable horror -- being kidnapped by a family friend who killed her mother and brother , and then spirited her away to the woods . A chance encounter with horseback riders who reported the pair to authorities led to her rescue after a brief gunfight between DiMaggio and Hannah 's rescuers . DiMaggio was killed . Hannah Anderson letters found at kidnap suspect 's home . While she has not spoken publicly since her release , she has seemed unusually outspoken on social media , where she has shared details of her ordeal and her feelings in response to questions from friends and strangers alike . Her postings on the social media site ask.fm -- since taken down -- have generated some controversy among some who question why she seemed so upbeat despite all that she had been through . They note she answered questions about what would in any other context be typical teen fodder -- boys , nails , hair and music -- among revelations about her capture and whether she is happy that DiMaggio is dead . `` Absolutely , '' she posted . Opinion : Are we sharing too much online ? But Robi Ludwig , a psychotherapist and co-author of `` Till Death Do Us Part , '' said the posts actually could be a sign she 's coping well with the trauma -- so far at least . `` I actually think it 's healthy and a sign of ego strength that here 's a 16-year-old girl and she wants to do what normal 16-year-olds do , '' Ludwig said on `` New Day . '' `` And I think it 's really smart of her to talk , to try to put what happened to her in perspective and the way 16-year-olds do . That is , they turn to social media , '' she said . `` She wants a support system . She 's getting that when she 's talking and interacting with people , so that 's healthy . '' Hannah addressed the issue herself on the ask.fm site . `` I 'm trying to stay strong . And get out the truth , '' she wrote . `` You do n't know I could be crying answering these questions at the moment . '' It 's in Hannah 's personality to try to be strong for everyone else , said friend Kylah Hayes . `` She 's really like an outstanding person , '' Hayes said on `` New Day . '' `` Like , she 's always like putting others before her . '' But , Ludwig said , Hannah is almost certainly in `` denial and shock . '' `` What has happened to her probably does n't even feel real yet , '' Ludwig said . Affidavits : mother , brother 'tortured and killed ' And that she would seem to look good from the outside , even able to talk about mundane teen interests despite losing two family members and enduring a harrowing ordeal at the hands of someone who had been a family friend should n't be altogether surprising . `` This is not the most difficult time for someone who is grieving because you have a lot of support of people around you , a lot of attention , '' she said . Darker times are almost certainly ahead for the girl , Ludwig suggested . `` The difficulty comes when everybody forgets and you 're left in your life , one year , two years , three years down the road , and the people and the crowds are not there . '' That 's in part why Hannah 's rural community came together Thursday to host a fundraiser for her . The money raised will go toward Hannah 's needs in the future . Any extra will be donated to support exploited children , said her father , Brett Anderson . He added his own take on how she 's doing : `` Hannah sends her love . She 's doing good day by day , and we 'll keep moving forward from here . '' CNN 's Casey Wian , Greg Botelho , Ed Payne , Matt Smith and Paul Vercammen contributed to this report .
Kidnapping survivor Hannah Anderson is `` acting strong for everyone '' a friend says .
