I would argue to disagree with ascribing mental health issues after the Millennials due to whatever is also relatively new at the time like kids having more supervision. This essentially boxes your theory to apply to only one generation (gen Z), so what you're describing is only that Gen Z are more mentally ill than Millennials, which... are you sure you can neatly form causal relationships between one generation to one specific change? How are you doing that?
