Met up with my mom after not seeing her forever due to college. She gives me a bracelet with crystals on it and tells me that it has anti-anxiety properties and will help me focus/study better. I explain to her that it's bullshit but she just laughs knowingly and tells me to "look it up." She's really struggling money-wise and I don't even want to think about how much these cost her (she bought some for my grandparents and my sister too as well as herself.)

Basically, how do you explain that this stuff is a scam to an overly sensitive person. When I tried to talk to her about it she just called me the "biggest sceptic in the world" and wouldn't budge an inch. I'm concerned that any pressure from me would damage our relationship but I can't stand seeing her being taken advantage of.
