My recommendation is to not make a scene about perceived injustices.
Instead of that, observe to see what is happening, take note and gather evidence for yourself, so you can decide personally the best course of action for yourself. Plan carefully the best way to move on with your life. Most of all, to your best to stop any injustice from continuing, spoken from my point of view as a child at that time, even drastic measures if that's the only possible remedy, but do this in a way that won't mess up your own life or that of others who are not part of the cause.
What I'm saying is that she's purposely trying to mess up your world, so put a stop to that now, mess up her world instead, but do it silently, without drawing attention to yourself. Meanwhile keep burning the bridges and moving on with your life. Instead of her taking away what you have, take away what she has, not for yourself but just take it away so she's not able to continue the abuse. An easy start, since she's dating a patient, is to take away her profession.
