Robin,
From what I have gathered in reading your question, you are a member of a special project. If you are reaching a burnout, it would be better if you resigned from it and join a project less stressful. Wikitree is different to many people. There are ones who enjoy genealogy so much that they are on wikitree 24 hours a day. There are others who enjoy loading gedcoms for a place to store them, genealogy can also be termed as a hobby and wikitree would be a great place to fine relatives. Granted, there are many duplicate profiles on wikitree, due to mistakes made by new members or gedcoms added without the understanding of what matches stand for. That was why the Arborist project was created, to find the duplicates and merge them.
Take a break and find a project less stressful. There are many out here who needs volunteers.
