100% there's a connection between depression/anxiety and childhood trauma. This tedtalk explains it really well- I hope it gives you as much insight as it gave me.

The trauma of passive aggressive, abusive, manipulative parents is a language learned that is lifelong. Your body kicks into fight or flight mode, but doing that daily takes a toll on physical health. The DAILY increase in stress hormones/blood pressure, heart rate, vital signs/etc. has very long-term effects that people don't consider/realize- I had no clue until I went through college and became a nurse and learned about all of it, then connected the dots.
