There are several sites all over the Web which provide suitable exercises for both beginners and more advanced healers and their patients, with reference to cleansing, revitalising and rebalancing the chakras, or our body's seven major psychic energy centres.
Here is one however that I would heartily recommend as at least a good place to start.
"Chakra Balancing Meditation"
http://www.reiki-for-holistic-health.com/chakra-balancing-meditation.html
Let me know whether or not this helps. A general grounding exercise would also I feel not go astray in calming you down.
"EVERYONE IS PSYCHIC" by Julien Plante
http://www.indigosun.com/june98/plante.html
See especially the section entitled "OPENING TO PSYCHIC ABILITIES THROUGH GROUNDING", as well as including further valuable information about the individual chakras and their commonly accepted roles within our energy (or etheric) body as a whole.
