Elisha Goldstein, Ph.D writes for the Huffington Post. Dr. Goldstein is also the author of The Now Effect and co-authr of A Mindfulness-Based Stress Reduction Workbook . I read his blog because he writes about mindfulness and how it can help with difficult emotions.
Dr. Goldstein uses an easy to remember acronym you can use when you have difficult feelings that can feel overwhelming. R.A.I.N.
R = Recognize when you have a strong emotion.
A = Allow and acknowledge that it is indeed there.
I = Investigate and bring self-inquiry to the body, feelings, and mind.
N = Non-identify with what’s there.
