God, what a horrible experience to go through. I cannot begin to imagine the kind of pain you're in.
Raindrop, the fact that you're able to get back to work in spite of all that you're going through shows an incredible amount of strength and resilience and courage on your part.
Would you consider seeing a grief counsellor? This is such an awful thing to have to deal with on your own. I think you might need a real person to talk things through. Not that we're not here for you too.
Please take care of yourself. The bikes will be there when you're good and ready, they're very patient that way.
