Well, there goes the neighborhood!!!
You will be missed until you get back Gary.
Along with cycling, for me music has power to improve my mood and make difficulties easier to deal with.
I just bought the Eagles new CD, and if you like the Eagles, I would suggest it as a good listen. Some of the songs have messages that help me, maybe you'll find the same!
Just avoid music that pulls you the other way. When I am depressed, I need to avoid certain music, like Pink Floyd... When "Wish You Were Here" with its dark mood is the closest they have to a happy song, I avoid it when I am feeling down.
For me it is Classical to relax, and Rock to get pumped up, and some Pop to cheer up. Your mileage may vary.
