I also used to see 'signs', since I was a teenager and even on the AAP's.
I enquired about the validity of my 'signs' in a biblical sense, and scripture says it's not real.
So now when I see a 'sign', I just remind myself that it means nothing, it's part imagination.
Delusions? A tricky 1 yes, my secret weapon? cold hard FACTS.
I have them written down, and when I'm doubting it, I read over it. If that doesn't help, I ask an 'anchor'. Someone who knows me and is actively part of my life. Usually my younger sister. She'll stop at N0THING to convince me my bf doesn't want to leave and all that jazz.
My point? Sometimes we just need to learn counter attacks for what our disorders do to us. I understand that everybody functions at a different level,and some can handle more than others, but I believe in trying.
I'm not an AAP fan, but they did help with my rage issues and voices. Neither problems have returned since quitting tho...
Sorry if this was a waste of your time, just wanted to add a different approach

good luck with the way forward.
