You are SO not crazy! That is why it is so important we listen to our true inner selves, and not self chatter, when we hear stuff like this, disregard what they, and try to know, that though we know need help of some nature, the docs are human, are not God, are not perfect, and can make huge mistakes; we need to throw out unsupportive crap like this and find someone who will support us. Even when it seems like there is no hope, there is always a bit of it hiding somewhere. It is just a matter of finding the right person, or doc, or T, or provider that can support us the way we need. It just may take a little more effort to find it, but it is out there, hanging by a thread albeit but it is hanging.... that is why we say, hang in there.

My theory anyhow.
I can completely understand why you found this so important, to distinguish between hypervigilance and paranoia, and about psychic injury and mental illness. I had not known about hypervigilance before, but it is interesting. I hope you found some solace as I did with it not only being illuminating but relieving in a way too; as with these distinctions, it helped me to know I was not completely losing my mind but was in fact reactionary in some instances, while further helping me to understand the nature and pathology behind how attributes/events could characterized to be helped. Lots of discussion to be had in the future with T; she has NO IDEA what is in store for her next week.
I greatly appreciate you taking the time to research it and in posting this. Thank you too Open Eyes for inspiring this thread. So informative you two. Truly, thank you! Wishing you well MJ on your path of discovery. Take good care meanwhile and thanks again!
