It very much sounds like you don't want to go to your aunt's, and I don't blame you!! I wouldn't either! My opinion, for what it's worth, is that it would only exacerbate the travelling issues, and likely be triggering (or at least upsetting). You've got enough on your plate as it is.
It's your decision of course(!), but if we were voting (

), I'd vote no.
Is your dog doing better? How are you faring?
