Here is a Grounding Visualization to try
The first time you try this, I recommend standing on grass or earth, not indoors. Stand with your feet solidly beneath you and about shoulder width apart. Balance yourself by swaying front to back and side to side until you find your “center”. Bend your knees a few times to get a sense of your energy circulating. Inhale deeply and exhale fully and repeat. As you continue to breathe deeply, picture yourself as a tree. Your arms and hair are branches. Your torso and legs are the trunk. Picture roots extending from your feet into Earth. Each time you inhale, feel energy coursing up into your body through your roots and into your legs, torso and finally into your arms. Each time you exhale, feel your roots extending deeper into Earth seeking new energy. When you feel “filled” then thank Earth and let any excess energy dissipate and draw your “roots” back into you. You are now “Grounded” in your body.
