My heart & prayers go out to you -- in your quest for Peace & Healing. There are so many ways, forms of meditation -- w/ guidance from an "instructor", tapes, books, etc.-- but even simple focused breathing can be challenge when the Mind is so full & busy... someone posed this @

www.beliefnet.com

website --in Meditation section.(access via their Search box w/ key word "Meditation") Perhaps you'll find suggestions there helpful; lots of articles & "examples" or numerous Links to other sites...that may be beneficial...
Good LUCK....
Blessings...
