Mental Health Support

and no one else can tell you what is or is not worth it to have a malady in your body fixed. Please don't be a martyr and give in to others' demands. If your sister had any empathy whatsoever she would not be strong arming you to give the money to her instead. While it is normal to want to save you from being taken advantage of by an unethical doctor, that does not seem to be her true concern here. I agree with the other posters who encourage you to get a second opinion. And if the cost comes in cheaper, that still doesn't mean that you owe the difference to anyone else.
