There were a lot of things that led up to my breaking point, but a 60 Minutes II segment that ran in the fall of 2001 was the clincher. It was about a 15 year-old boy who was suffering from sickle cell anemia (a terrible disease), and the treatments he was constantly undergoing were starting to become ineffective in slowing the progress of his fatal condition. So his doctor decided to try an experimental treatment: a transfusion of umbilical cord blood. The blood that he received was a different type than his own. The transfusion changed his blood type to the donor type and cured him of the disease, and I thought that was fabulous, I think I even got choked up and cried a little I was so happy for him. Here's a link to a synopsis of the segment:

At the time I was in crisis over my association with JW's, I felt like I was going crazy and I had problems with a lot of aspects of JWism, the blood issue being a big one, but I hadn't searched the internet for information and was still basically a believer, though a very miserable one and hanging by a thread. But the dam broke after that segment, I started to really question things in a serious way, without employing the usual stop-thought techniques that I had developed over the years. I attended one meeting after that, but it wasn't the same, and soon I was searching the internet to see just what those wily 'poztates were saying that the WTS was so desperate to keep me from seeing. :)
