Hope you’re holding up ok ☹
I’m not sure why that person thought they had the right to tell you what you can share with the world. Your thoughts and feelings are just as valid as theirs — never apologise for them.
This situation reminds me of a quote from the infinitely wise Stephen Fry:
“It’s now very common to hear people say, 'I’m rather offended by that.' As if that gives them certain rights. It’s actually nothing more... than a whine. 'I find that offensive.' It has no meaning; it has no purpose; it has no reason to be respected as a phrase. 'I am offended by that.' Well, so fucking what."
