I can totally relate to how you feel about your art and how there are periods of time when you just can’t produce art to the level or frequency that you’d like. For myself personally, I get creative blocks if I’m undergoing a lot of stress or anxiety due to my job or my personal life. I recently, within the last few months, had been going through a period of a creative block that I’ve never been through before to the level that it was at. It came down to me removing certain things from my life that were causing me to be stressed and anxiety ridden. A major one was quitting a super stressful job that was effecting my creativity and allowing my brain time to heal. That was essential to me recovering and getting my creative juices flowing again! I hope you will be able to do something to relieve your brain of whatever is causing it to not perform. :)
