I would 100% believe she's BPD and narcissistic at the same time, but honestly, these are just different psych-approved ways of calling somebody an asshole. Here are the important points as I see them. She's entirely incapable of taking anyone else's opinion into account and if you disagree with her she eventually just starts making nasty shit up about you. She cuts herself and, while she isn't fat, her body shows signs of severe eating disorder weight yoyoing which has irrevocably fucked it up. She literally wants to kill babies, not in a "ha ha dead baby jokes are funny" type of 15 year old boy way, or even in an abortion enthusiast kind of way (though abortion is indeed murder), but in a serious psychopathic kind of way. She despises men, also in a serious psychopathic "wishing death on them" kind of way. On top of all of these red flags, she's an attention whore who delights in forcing other people to witness her dysfunction.
