Ground yourself. And Drink some water.
Except from another site---> A simple Grounding technique
Bring your thoughts from busy mental chatter downward by focusing on your feet. Don't rush this process. Take your time moving from each part of your body. Also, you don't need to touch yourself, just allow your mind to switch focus from wherever it is. Begin with your feet and move upwards.
Notice the soles of your feet, your toes, in-between your toes, the top of your feet, the back of your ankle.
Do they feel hot? or cold? Do they hurt? Are they numb? Do you feel your blood circulating through them? Are they feeling tired?
Don't judge how they feel - just notice how they feel. Wiggle your toes. How does that feel?
Once you have a made a strong connection with your feet you may then move your attention upwards to your ankle... then switch focus to your lower legs, onto your knee caps, behind your knees, your thighs, and so on.
Keep reminding yourself not to rush.
Allow yourself to breathe throughout the scanning process, especially as you come to any areas of discomfort (stressed muscles, soreness, etc.) or at any spot that feels like there may be an energy block.
Once you have moved through your torso and up to your neck, drop back down to your fingertips, move your attention to the hands, up your arms and shoulders, returning your attention once again to your neck before finishing up with your focus on face and scalp.
This is a simple meditation which will bring body awareness.
