I see a rut as an ebb in this life, but it's important to ride it even though the way you ride it will be different than normal. It's also important to note that tons of folks feel this way because it seems like we're all just hoping for some precedented times...
Small changes in a few different areas, and at the same time, could spark something. New routine (sleep/wake time), a t-break (stepping away for a few weeks always helps me), a new hobby (a bike and some time to ride it), and even something as menial as cooking yourself a few meals can drive some fulfillment. Hopefully it can spark some creativity elsewhere like your game and your job. If anything, it will create a fun sort of experiment that you can move through and pick up small wins.
