It seems that the part of the brain drives them to voraciously acquire information about the world, also brings oversensitivities in thinking, "What ifs." They're just wired that way. I'd wager that the higher the IQ, the more hypersensitive they are. This is one of the sources of stress for us as parents; these episodes create more jobs for us, dragging us along on the rollercoaster of their emotional upheavals. I think it's important for parents to take breaks, dates if you will, as they need breaks from the intensity. Ours is 27 now and it was a hard road, but worth it now that he's a wonderful adult and soon-to-be prof. Also, I'd wager that the more hypersensitive ones are also the most argumentative and exacting.
