I feel for you ..... I've lived in our home thru many renos ... and have lost my whole interest in doing more. Right now I want my bedroom painted ... and quite honestly, I just feel like it's another reno and keep backing away from it!
When the going gets tough ... do what I have done ....... and keep saying to yourself ... "KEEP YOUR EYES ON THE PRIZE"
It'll be well worth it, once it's done, and yes, some anxious times during ... which hopefully later you can laugh about.
