I ran across this phrase in a video made by an Australian walking the Camino de Santiago. He describes a horrible sleep-deprived night and suffering from food poisoning, and states that he's feeling a little precious. https://www.youtube.com/watch?v=4dqOI87nSU0 at 1:09:25. I assumed from the context it meant wasted or shaky. In this blog entry there's a similar use, I believe also from an Australian:
It was a good night as everyone celebrates throughout the city just as we do at home. Woke up the next day feeling a little precious and was having a coffee and looked at a stamp I had on my hand from a bar we went to.
But then, in this blog, which is also an Australian, it's used a bit differently:
Matt is feeling a little precious about a couple of scams he's fallen in to over the last couple of days. The first one was when he asked me the time one morning and I mistakenly read my watch as 6.30am - off he went running at 5.30am. He was a tad confused to get back at 6.20am. The second I will let him explain but when you read it bear in mind how many years he spent dealing with reps and suppliers getting the best possible price for shop stock. Right Matt here. Absolutely gutted yesterday got conned by a gypsy woman about 4 foot 6 and with only one tooth.
In that case, it seems to mean disappointed or embarrassed.
So, what's up with this?
