I have found meditation to be a wonderful tool for grounding me and helping me to regulate my moods. If you are interested in exploring meditation, there is a great app "Insight Timer" which has guided meditations, groups where you can ask questions, music, and lots more. Another resource that I found helpful to structure, inform and motivate me at the beginning is the book "Mindfulness: An Eight Week Plan for Finding Peace in a Frantic World". Really the only requirement is to begin to make a little time each day and begin to sit quietly. If you are interested, there are many books available to help with your understanding of meditation.
