In defence of not tagging, I used to have a trigger word (before tumblr / before I knew what they were called), I would have terrible panic attacks if anyone mentioned passing out or suicide or if I saw blood or if I thought about going outside. But I never expected other people to cater to me, because I didn't want to live in a world where people couldn't be normal around me, I just wanted to be normal with them. And now I'm better. People need to realise that avoiding these words is unhelpful.
