I had a sudden epiphany a few minutes ago: I can return to work on my wooden tile project! It's all tiny individual pieces that get combined in various ways to form a larger piece of art, which is perfect for how fragmented my thinking is right now. I can just work on these small, simple components of a larger piece & not worry about how it will all fit together. It can all fit together later.
This project seems ideal for how I'm feeling right now. I wish I'd thought of it sooner! I'm sure it will be distracting and fun, and it'll give me a chance to be working on an art project again.
