I know that the initial characterization of bpd as being the borderline of neurosis and psychosis is generally frowned upon, but I personally feel like it's completely spot on. I basically alternate between being incredibly perceptive, detail oriented, and obsessive, and then pretty much losing touch with reality and retreating into my mind and it's warped perceptions that I ironically come up with and rationalize while experiencing 'neurosis'. i.e. i over think and over analyze everything and then i have a mental breakdown over my conclusions and try to detach from everything as a defence mechanism. usually i exist in a bit of a limbo, since obviously both extremes are just endpoints on the axis spectrum of my emotions, ive never went full on schizo (for lack of a better descriptor) and I've never been totally neurotic, since the two basically act like magnets that more or less stabilize each other out; but notheless I do feel like I strongly experience both mental states, at least more so than the average person. anyway ye hopefully that makes sense, idk if anyone else can relate.
