Thanks -- I am such a stick in the mud when it comes to holidays, I just sit at my usual spot on the computer.
As for Si, I think the secret is to take tiny steps and carefully analyze your mental/emotional state after each step that you take. I doubt you would, like, start going out with her or something. You've been through too much to go down that rabbit hole again. But keep an eye on your state of mind and proceed with caution. I actually think your blog here is a great way to do that.
It sounds like things are going pretty well in general. The scary part is the May 1 meeting. My fingers are crossed for you.
