I had a friend that I thought I'd someday be sharing a retirement home with completely, irreparably cut me out of her life. I thought I'd eventually get over it, but it's been 5 years now, and I still can't let my guard down enough to make more friends. Getting hit right in the INTJ loyalty is hard to handle.
Anything would help. All the advice that other, non NT's have given me has been utterly useless.
