Yes, I am seriously mentally ill. I'm in therapy, on medication, and currently orienting my life to focus on getting better (I stepped back from career progression). Do you think I introduce myself as, "Hi, I'm Mezzie, my triggers are X, Y, and Z?" I mentioned my illness in this context because it's relevant. Talking about something in a matter of fact way when it's relevant to a discussion =/= 'advertising' it, 'celebrating' it, or 'wallowing' in it.

I also mention my Multiple Sclerosis when it's relevant. Is discussing my spasticity 'wallowing' in it?

Why is your first instinct to shame the suffering person for talking about it? We shouldn't celebrate it, but nor should we ban any discussion of it socially because it makes you uncomfortable. I'm sorry that you clearly have emotional reactions to frank discussions of mental illness; are you in therapy for that?

And again, work on your reading comprehension. I'm arguing against trigger warning culture because even if I take its assertions at face value, it doesn't help the people it purports to help. It's a refutation of the argument that 'trigger warnings help people with PTSD'. I have PTSD, which is relevant to refuting that argument. That's why I mentioned it.
