You sound exhausted, which is perfectly reasonable given what you've been going through. Is there any need to rush on the DWR? (I can't remember if you said it was for a specific milestone/date/deadline)
I think you need to rest and recover a bit first. Putter about a bit. Let your mind and body come together again, lol. I suspect you'll find that putting the DWR together goes faster and easier if you give yourself time to rest now, rather than forcing it.
The other thought that occurs is if you are just not inspired by the thought of doing a DWR, or the chosen colour scheme, any more? Does another pattern/fabric appeal more? Or is it literally the thought of doing any quilt that is unalluring right now?
