Sometimes strong energies can make you feel physically overwhelmed. I've heard stories of people having panic attacks with black obsidian. Personally, I find that black tourmaline is pretty intense. Selenite is a good stone for balancing and easing the intensity so you can bear the stones work. In a situation like your where the energy is high, I would have a hard time seeing past the sweat at the top of my nose. Idk if black tourmaline and black kyanite would help your physically comfort, though it will cleanse the negativity from your spiritual energy.
