Any crisis of creativity is rooted in the brain. Therefore, the solution should be based on understanding how the brain works. Most of the time we get so immersed into texts that we can hardly perceive visual information, sounds and tactile sensations. Arrange a "sensory reload". In media, we mostly work with our eyes. So it's necessary to turn this channel of perception off temporarily.
Get everybody out of your room, ensure silence, turn off the light, put on a blindfold, sit in an armchair and concentrate only on what you can touch with your fingers. Feel the roughness of the paper on your desk, the ribbing of the pen you usually write with, find a crack in the glass, examine your computer mouse with your fingers. You can turn on some relaxing music, listen to it with your eyes closed, focusing on the melody.
Dance like nobody watches you. Go for a walk just to wander around. Make yourself to go for a walk, right now.
