I feel like I am having a flash back! This is the exact thing that has happened to me! I was brand new to genealogy and thought I had done something wrong. I am now working on FTM alone and not synching. It took me almost a year to get my FTM tree and files in any kind of understandable order. I too work full time on this 8 to 10 hours a day. I inherited 2 books from an uncle and had entered all of both books and was in the middle of attaching sources to these 3000 people. I cried for a week and almost gave all of the inheritance" to another family member to finish the research. I am now glad I didn't because I have learned so much but I can certainly empathize with you. You are in my prayers.
