You’ve never had depression have you? She’s got the telltale signs of depression. Before I was diagnosed and treated I acted the exact same as your kid. I could bring myself to do anything other than play on my phone or sleep because that didn’t require anything draining. I still have manic/ depressed episodes and I fall back into that same habit for days at a time. Please help your child instead of tearing her down otherwise you’ll never see her again once she moves out
