Garry ... what can I say? I'm feeling for you ...
Most of us have at one time or another gone through one these heart wrenching episodes; it all becomes past history though, as Geoff says, and in my case at least, was by far the best thing that could have happened for me.
Keep that guitar handy, you're going to be doing a lot of writing. Make sure you record all your ideas! You can turn this into a whole album.
Hang in there, Garry ... we're all here for you.
