I think you could benefit from focusing less on these medical definitions and more on trying to figure out your own personal needs and boundaries - those are what really matter. I know we need to sometimes surrender to these definitions for the sake of getting support (E: which knowing our needs and boundaries better, informs better), but that it in itself is a form of gatekeeping (not yours, the medical and social institutions), that we shouldn't have to apply to our own thinking of ourselves.
Sorry to info dump, but these are a few links that might help you think about things a little differently:
