Denise-
There's not much I can say that hasn't already been said here. My deepest sympathies - I have to echo what Emily said - please be kind to yourself during this time. You'll move through the grieving process in your own time - in the mean time, hang on to the happy memories.
It looks like from crazyguy you're still on for your trip - please do try to enjoy yourself...It won't be the same, but let the happy memories come through and let yourself grieve and heal in your own way.
Please let us know if we can help in any way...
