I love this, if only because I could relate to it. Donating blood was actually my biggest fear. The reason I did it was because I wanted to face my fear. I'm still proud of it! You seemed to have lived a crappy life. I don't even remember ET now.
I was just afraid of losing blood. Luckily, it was painless. Kind of like yours. I was lucky enough not to get in trouble with the nurses like this. You should donate bile.
