I feel for you on this new revelation of EA/PA. I have not had to deal with this and can't imagine the knife in the gut this probably brings with it.
I just want to challenge you on the seeming rush you have to file. If you look back just 10 days ago you wrote "I feel that there is true hope for R at some point."
Perhaps the EA/PA is the deal breaker, and if that's the case we'll all have your back on this decision. Having said that, I'm all for letting the dust settle before making a final decision, especially if you have other things going on for the next few weeks.
Maybe if you need to take some action to feel better, print the forms and fill them out, but sit on filing until you are in a more relaxed timeline?
