A few that might work...

CSNY-Carry On
Cortez the Killer, by whoever does a good version (They are all good IMO) I dunno about how the lyrics connect to your situation, but it couldn't be any more mellow and laid back.
Gov't Mule-Soulshine
Arc Angels-See What Tomorrow Brings
James Taylor-Fire and Rain
Pink Floyd-Wish You Were Here
Trey Anastasio-Shine

You should check these out... I don't really know the mood you're going for, although I can only imagine what I would want in it. Really sorry about what happened man.

Oh, sorry, I just read that you only listen to heavy metal. :rolleyes: Still check these out though. You might find that one fits the situation well. Oh, and a "heavier" one I considered was Joe Bonamassa- Had To Cry Today
