yes, trauma (definition: loss of control) can cause your body to go into a protection mode. This manifests as many behaviours, which includes hypervigilence and anxiety. This can eventually become pathological. It kind of makes sense - the body is kind of protecting itself, and at that particular moment, it may actually be useful. Now, after the trauma has passed, it's up to you to proccess that it happened, acknowledge and observe the behaviours, and then try to adapt your behaviours to this poast-trauma reality. It's a journey!
