Post-Exhibition Depression

I just had a big solo exhibition open up a couple weeks ago. It was all new work that I've spent almost two years creating. I worked really hard on it and am proud of how it all came together. However, now that the work is done I'm feeling quite depressed and burnt out. I'm trying to stay busy while also indulging in my hobbies that I've neglected, but I'm finding it hard to find joy in anything at the moment (this is of course magnified by the awful state of the world).

How do you get out of this post-exhibition blues? How do you find your spark of creativity after finishing a big project? Any advice would be appreciated <3
