The thing is - and I say that from experience (being somewhat on the ADHD spectrum myself) - that there are no limits to how many of these you can use; or at least that’s how it feels to me (sorry!).

I am guilty of overusing em dashes — I just think they’re aesthetically pleasing, even if they’re often unnecessary.

i do this; i just have so much to say, and there are only so many conjugations and commas you can get away with – without it becoming a run-on sentence (i may have a run-on mind).

Semicolon ftw
