I definitely understand how you feel, and I'm a bit the same! I have been working hard for so long and now everything seems to be going a little pear shaped :( Just give it your best, and good luck!
Lucky / unlucky for you. It was certainly challenging. The more I think about it, the more I think, how could they have made one little piece of a dot point a 12 marker?? (that was for Farming for the 21st century). Hope your head is ok!
