My mom stopped trusting anything I say and I don't know how to reach her anymore.

I don't really know where to start. Over the last year or so, my mom has gotten really into a lot of "alternative" content online, the kind of stuff that started with health and wellness groups and slowly turned into something else entirely. Now she spends hours a day watching videos and reading posts from accounts I've never heard of, and she talks about "doing her own research" like it's a personal mission.

The hardest part isn't even the beliefs themselves, it's that our relationship has changed. She used to ask my opinion on things. Now if I gently push back on something she says, she gets defensive and accuses me of "not being awake" or being "brainwashed by the mainstream." We used to talk on the phone every few days, and now those calls feel like walking through a minefield because I never know what topic is going to set her off.

I love my mom. She's not a bad person, she's scared and she genuinely believes she's protecting our family by staying informed. But I feel like I'm losing her a little more every month, and I don't know how to have a relationship with her that isn't just me nodding along or getting into fights.

Has anyone found ways to keep the relationship intact without either pretending to agree or constantly arguing? I'm not trying to "win," I just want my mom back, or at least to not lose her completely. Any advice on how you've navigated this with a parent would really help right now.
