You don't have to go any further. Open your eyes if they're closed. Feel your feet on the floor and the weight of your body where you're sitting. Look around and name three things you can see.
If a feeling is close and loud, try giving it a little room: that's there, and I'm here. You're keeping it company, not becoming it.
If the distress stays with you, reach out to your facilitator, therapist, or someone you trust.
