I can’t always answer everything, but it’s always ok to ask.
I don’t get triggered just by seeing stuff mentioned, so you don’t have to worry about that. There’s stuff I can’t write about because it’s triggering (and some things I write about even though they’re triggering), but just seeing something mentioned won’t hurt me.
(I’m posting this because some people express that they’re unsure whether the things they’ve asked are ok given that they might be triggering; I’m assuming that means some people aren’t asking at all out of similar concerns.)
What I can answer is not entirely predictable, but I do always try. (And sometimes weeks or months later I figure out how to answer something I couldn’t at first).
