That sounds really frustrating, kharma.
If I remember correctly, you're in nursing school and your mother wasn't very supportive of that. Do you get the feeling that your mother feels threatened or jealous? It sounds like your mother is splitting (
BPD BEHAVIORS: Splitting), or labeling you as "all-bad," which can be very painful.
You feel like you've shown her empathy and visited enough, though, right? How are you holding up?
