Sounds interesting. My previous career was as a vet nurse and I still do some of it for friends so am always interested in that kind of thing. But totally understand about the shush factor. My topic is something I have been in the vicinity of but more to the left and more in depth. It is true what you say about the complete story. I sometimes feel I will be doing a lit review for three years before I even understand enough to do some research. lol.
Anyway good luck with it. You will get through it and then will forget all about how you feel now.
