Your amygdala is the fear center of your brain. Once it starts sending signals throughout the rest of your body, you will likely have sweaty hands and feet, a rapid heart rate, and maybe some nausea and dizziness. Everyone's reaction is different, but these are my main anxious symptoms.
I like to use breathwork to calm myself down. Of course, this is not a substitute for dealing with your trauma, your impulse control, or major life stressors that are causing the anxiety, but it does help.
