Wow. I, like so many others here, did not realize that my tendency to obsessively and unwillingly sink into fantasy life could be related to BPD.
I am so sorry you're going through what you are going through, BrokenNBeautiful, but thank you for being so open and honest about it. It's very likely that you're helping others; you certainly just opened my eyes. I wish you the absolute best.
And also, to Longleaf - "impossible to switch off": well put, thank you.
