By the time I saw this you may already be off line but I wanted to respond and wish you the best in your move. It sounds like there are many positives with the new house and location once you can get settled.
I have many times wondered the same thing as to when my CRPS started. My time line is much shorter from initial injury (Nov'14) and my injury certainly less severe, but it is a question I have had many times. Why and when? Your story and injuries are so complex it would be hard to say at what point you met the criteria. You have been through a lot!
Take care and hope to hear from you again soon.~mac
