I have had a history of factitious disorder and borderline personality. I have been diagnosed (for real) bipolar 1 disorder (mixed features) with psychosis when unmedicated after suffering from a traumatic brain injury in 2016. That is when I started to look around myself and ask myself how I got that way. God held up a mirror and I didn't like what I saw.
You are welcome to message me or ask any questions about recovering from this. It is possible and there is always hope.
