I often feel sick when I'm anxious because the two are so closely related. Anxiety gives me an upset stomach or makes me dizzy. My T always comments when I'm holding my breath which I do a lot during therapy. I take sips of water, and she asks if I can feel my feet, my legs, ie grounding exercises. Does your T do that? Do you mean you feel like throwing up during your session? I imagine that would be emotional but could lead to the physical. Can you discuss this with your T? I'm always telling my T my physical symptoms.
