A "52" or picture a week project can be a daunting prospect and if you fall behind, it's very easy to get demoralised or demotivated.
A couple of things have just sprung to mind. Ask yourself why you take pictures and for whom. What is it you enjoy? What really lights your candle?
About 10 years ago I was lucky enough to go on a fine printing course run by Barry Thornton. It was an incredible learning experience. At the end of the course, he looked at my work and then said "take pictures of things that bother you".
So I did. Eventually, I had enough material to enable me to mount my own solo exhibition called "My Home Town".
So, why not think about what bothers you and try to photograph it? It worked for me, so it might do the same for you.
Ultimately, I wouldn't worry about it too much. If needs be, do something completely different. When I was in the doldrums during the latter quarter of last year, I learned to bake bread. We haven't bought a shop-bought loaf for months.
