Right now dealing with very heavy grief after a very recent loss. What has worked a bit for me is an app called Pigment. It’s essentially a digital coloring book. It’s mindless enough to keep my brain occupied but not demanding enough that it requires a lot of focus.

I do this while simultaneously listening to a streamed TV show. (Currently, Brooklyn 99). It’s lighthearted and positive, but not forcefully or heavy handed.

Hope this helps.
