If you've got a genuine block, get away from it.
Take a good break. Not a 15-30 minute break. If you've written yourSelf into a wall, you gotta back of and let your brain breathe.
The art won't leave, so don't worry about stoppin' for a hot minute. Oversaturating yourSelf in the art isn't going to help you or your music.
Breathe...breathe...
Peace.
