I'm thinking... that you might also need to tell her (possibly over and over?) how you are now trying to educate yourself about this disorder. (Remember, you have been acquaintances for 3 years and she hadn't even explained "triggers" to you.)

And, find items on the net (as she won't hear you, imo) how she needs to square herself away before trying to help others. (To me, I can't imagine how she can counsel others as she would be triggering and reacting to herself!) just my opinion

I admire your efforts. It's a big challenge you've taken on.
