I am so sorry for the huge scare you guys went through! Is J squeamish about blood, maybe?
There was a time I was giving blood a long time ago and I happened to look at it --- I have learned my lesson and I don't ever make that mistake anymore: I blacked out -- with spasms and twitching. The IV came out and blood went everywhere. Scared the living cr*p out of the attending nurse.
Now I just know not to ever look. Funny thing is I am a-okay with other people's blood. But if I see my own like that, I guess I can feel my brain draining.
