Hello, I'd like to help you with your question.
It sounds like you have put a lot into your relationship with your doctor. And while it is good that you are working on getting better and want your doctor to be happy with your progress, there seems to be more to the situation.
It seems that you have formed a bond with your doctor, one that goes outside the normal doctor/patient relationship. She has been there for you and you have been able to rely on her for emotional support. It could be that there is a lack of similar support in your life and by having a doctor that is so empathic, you have formed an attachment to her. Now that she is leaving, this attachment is ending and it is hurting you.
While it is perfectly normal to form an attachment to fulfill an emotional need, seeing this relationship and what it means to you can help you with the situation. Your doctor's role in your life is to be there to care for you physically and offer support. But for you, your doctor has become a focus and a significant support. It also may be that she has taken on a parental role, since there is a need to have her be happy with your progress.
It may help you to talk to a therapist about your situation. Getting to the root of why this relationship formed and what unmet needs it is fulfilling for you can help you. Also, talk with your doctor about making one more future contact with her, when you feel at your best and in your uniform. Ask if it is ok to send a picture and an email, just so she can see your progress. Then work on ending your relationship with her. It is a loss to you because of your emotional attachment to her, but working through it will help you see that you can get your needs met elsewhere, such as with family or friends.
