I'm glad to hear that you've finally gotten some answers as to why you're struggling so. That's what I suspected...that a tight wrap was the culpret, and the "reflux" feelings were a result of food getting hung up at the wrap.
I wouldn't worry about the motility issue...my guess is that your esophagus is struggling to try to get food through the wrap and it's messing it up. Hopefully once you get your wrap loose enough to allow food through more freely, the swallowing will become more normal again.
As Kitt so wisely suggested, take a deep breath and try to relax. Worrying right now can only make things more difficult. You'll go to the GI doc or surgeon and get a dilation, which is not all that uncommon. It may take more than one, since they'll want to gradually increase the looseness of the wrap. Hang in there. They'll figure out a way to get you straightened around.
