I do feel the need to balance these posts with a positive experience.
Even though some "friends" that I would have expected would attend my mom's funeral didn't (she was a 50+ years faithful JW)...when my wife developed cancer and was getting treatments at a clinic hundreds of miles from home, not only did she get visits from a local congregation who learned of her condition...but me, the healthly one living alone at home, also received visits from my cong that included hot meals
I agree only to a point. When I had surgery for cancer 15 years ago, a sister in the congregation organized several meals delivered to my home and my JW cousin drove several hundred miles to help me out a few days. What I've observed, not only personally, but with others in the congregation and neighboring congregations is that there is sometimes an initial flurry of concern - then it dies out very quickly. Also, it seems to be quite rare that there is any concern from the elders themselves--it's usually comes from maybe one or two individuals in the congregation on their own initiative--maybe..... Anyone in a long-term situation - like my mother (over 6 years) - is easily forgotten, especially when it looks like there is no hope of their ever becoming a useful member of the congregation again.
I think many JW's would like to do more charitable work in their heart, but they are always being guilted into more and more field service - putting any works of charity on the back burner. I remember one sister that said she would like to come and visit my mother, but she couldn't because she "had to auxilliary pioneer next month."
