Hi dolphin,
I'm sorry to hear that your Reiki teacher didn't resonate with you, that's hard especially with Reiki I.
Grounding: Close your eyes and visualise/imagine roots coming out of your feet. Let them go deep into the earth, through the soil, through rock, now anchor them onto a large stone or crystal buried deep within Mother Earth's surface. If you are well grounded you can send excess/unwanted energy out via your feet.
This is one way to ground yourself, hope it helps :)
Gentle Blessings
Helen
