Forgive me for not reading the previous replies other than your own. I think in doing so, I won't be influenced and might come up with something that someone else. hasn't suggested.
Take a break from writing: days, weeks months. You'll know when it is time to return. If you love to write and play, you'll know exactly when the time is right. I had to do this recently as my working life didn't allow me to indulge in the writing process.
I always knew that I could write and would never suffer writer's block. There comes a time when you understand that writing is an essential part of who you are and it is then that you will find the desire to express your creativeness. After several months, I was starting to wonder if I would lose my writing ability (that's really quite silly since I've honed my writing skills to a point where they will simply not desert me). I then quickly wrote a song to reaffirm this. Feeling quite pleased with myself, I then waited a week and still I had a burning desire to write. In the following week, I wrote 6 more songs. None of these songs are substandard. I believe that they are first-rate compositions. The main thing that i did notice is that my writing voice was refreshed. I'd hate to say that I have a favourite as they all carry a poignant message. Along the way, I wrote a song called "Houdini in Shackles"

It isn't forced and neither are any of the others. I decided that this would be a great title for an album. I have now produced 8 songs for that album, all to a high standard. Strangely, the first song "Don't Drown In Blue", which I will always have a soft spot for, hasn't yet been produced. (I must get round to doing that).
When you return, there will be many ways to write lyrics. It's not always my technique but I would consider writing to a title. The title should present many ideas. In the above example "Houdini In Shackles, I decided to read about the escapologist, what he did, what his beliefs were, how they aligned with my own, and how I could relate his life and adventures to my own thoughts and considerations. It really is quite a simple way to write but the end result should be sophisticated because of your research. Choose a topic; there are so many. Off the top of my head, The James Webb Telescope would be a great topic. I'm already thinking about who invented it, obstacles faced by the designers and engineers, its purpose, what scientists and astronomers thought it would discover, what it has discovered, what it tells us about the past, how it might impact our future etc Relate your findings to an aspect of your life, the lives of other people. Relate it to human emotions. The possibilities are endless.
It's your task as a songwriter to organise your thoughts and to bring something creative into being.
Good luck!
