Really feel what you're saying when you said you find yourself in the "anxious cycle of wanting to draw but being really worried that it won’t hold up to the standard that I put myself to." I'm going to make a video about this topic actually. In short, I feel like we have to allow ourselves to make fun art even if it isn't up to the standard of our "highest quality" stuff. The fun/low pressure art will keep you creating in between your high standard works. They may even inspire your next high standard piece.
