It also goes together because the nervous system slows down the nervous system during stress. I often have to go before doing something stressful and I’ll feel anxious at the same time. I think it’s a trauma response or my body learning that I’m about to have a period of time my body is activated with stress, so it better clear out while it can. So do I feel anxious because I am afraid, or am I feeling anxious because I’m actually having a gut reaction ahead of a stressful event. Probably both.
