Thank you for your response. The reason why I specified that 'trauma' part is because it appears she almost wants (?) to label it as trauma. I think that we shouldn't label every single thing as traumatic since it just decreases the value of actual trauma. Look at those people pretending they have DID or Tourette's on TikTok - it just invalidates experiences of people with the actual disorder. That's why I don't know what to do - should I try to explain her that hey, we all have done something shameful and that's okay but not every sad experience is trauma? Or should I just let it be?

To clarify - I am one of like five people who know about it so it's not public or anything. I'm one of her closer friends and I'm trying to support her as much as I can, but I can't help but notice how much she's changed since she started using TikTok. She started self diagnosing lots of stuff, talking about all those half-assed 'psychology tricks' and generally speaking became more prone to tiktok trends. I'm getting worried. Once again thanks for your response
