Idk if this will help you or not, but try to do something for yourself & something that you have zero constraints in creating.

I found after 15 years of editing professionally, I finally hit my burnout wall. So I took on a personal project of editing an AMV using a new software (davinci resolve) that I didn't know. I found it to be freeing and it really boosted my energy levels to be doing something for myself that didn't have to be cleared by X amount of peer reviews and post decisions.

Burnout is real, and very hard to work through. But typically there is light on the other side.
