I notice that there are a large number of Youtube videos offering possible relief from the mental torments of life. To see some of them, go to youtube and try any of the following search strings, parentheses optional:
(pain relief) (depression) (anxiety) (stress relief) (guided imagery) (sleep)
You'll see lists of videos offering pictures and music intended to help.
I know these won't work for everyone but they might help some of us. I myself have sometimes gotten more relief from pain (not cancer pain fortunately) from music than from drugs. I keep mp3s of some of my favorite music on my smart phone and sometimes when I wake up in pain in the middle of the night, I turn the sound on the phone way down, put it next to my ear, start the mp3 player, and wake up later to find that I fell asleep and missed the last movement of the piece.
I am curious to know if music or videos work for others. If so, please let us know and share what works for you if you like.
For me, I've gotten relief from Beethoven's Piano Concerto Number 1 and Symphony Number 6, and Dvorak's Symphony Number 8. But I know that there's lots of Jazz, Blues, Pop, and other music that will work.
