Never in my life had I experienced anxiety until after I lost my sweet wife Pam. For that matter, to my knowledge nobody in our family ever suffered from anxiety. It is absolutely a mystery how it comes on and causes the brain to go round and round in circles while the body seems to have a need to be in constant motion. Thankfully, I'm found some ways to over these attacks of anxiety. However, it does take some effort and will generally not just go away on its own.
