Just really question what u feel like reading, and dont force it.
Reading blocks happen, so I just take a few days off, but find a different way to interact with the language. Watch some TV each day, or maybe read smaller articles. The desire will come back :)

it is for French, my French is about upper intermediate and the materials I'm reading are not hard to read. I'm just not feeling motivated these few days. I don't know why.
