Is an Auto Accident emotionally traumatizing?

[Carrameow]

A lady friend of mine has lost 22 pounds, gone into a deep depression with anxiety attacks and sleeps badly after being rear ended last fall and suffering lower back damage and pain. She needs muscle relaxants and painkillers which dont help the issue! She also has nightmares and when I lost saw her, she looked very sick and frail.
I have a few collateral points to raise. When it comes to mental, physical and spiritual toughness there is no difference between men and women.
I've clumsily trashed two cars, one my 300D which was squeezed like a stepped on soda can, and escaped without injury or emotional trauma, as well as fallen off a roof unconscious.
Believe me I am no Iron colonel, I have my equally terrifying or even more terrifying feelings on other issues, and I've had nightmares and fears when it comes to my job, my job performance, approaching 50 and losing my loved ones or being incarcerated ( Could you imagine being locked up? No tools, no creative outlet, no 300D to work on.)
Have you been in a serious accident? How did you feel afterwards?
