I’m sure the first thing the doctor will do is take her off social media. I’d go a step further and take away a smartphone completely. She will feel like you’re punishing her, but just let her know it’s not true. This is what a good parent would do, and you really want to be a good parent. The research on adolescent girls and social media is overwhelming. I’d also recommend taking a family trip with no phones and reengaging. There’s an excellent book called, Hold on to your Kids by Gabor and mate that explains why kids’ primary attachment must be their parents who love them unconditionally. The last thing may seem counterintuitive right now but I would require more of her. Children and adolescents need work, hard work, to feel capable, valuable and like they belong. If it’s work outdoors even better. Keith McCurdy is a LPC that talks about raising sturdy kids and he’s been guests on several podcasts you can google, talking about anxiety and depression in teens being directly related to a lack of adversity. He also addresses negative confirmation bias and how we need to equip our teens to use their emotions as a gauge and not as a guide for how to live their lives. Emotions are real, but not reliable for decision-making. I prayed for your family just now!
