Improving handwriting when exhausted & slightly psychotic?

Hey,

I'm annoyed that when I am in certain super cluttered mental states, that I can't read my handwriting after.

My handwriting generally isn't great, but I used to do shorthand for journalism, so I know how to write readable. But it requires some strain, especially in these states, where the focus is lost on what I actually want to write. So either I write clearly then, but won't be able to free-flow, because I strain on the writing, or it's unreadable after.

Usually I'm just scrambling to find a paper and pen, since getting to my offline laptops and booting them up is too much. But I'll also be getting a mini-laptop now for this purpose.

Still, though, I feel like there should be something that can be done.

Thanks for your help :)

E: I'm talking about a situation of being myself with stuff that needs to be let out, not doing professional work or similar.
