"It has been 4 years of hairloss, tiredness, blurry vision,headaches, and weight gain!"
You said it yourself. Just say it louder. Good luck. Only you can do it.
You have to be your best advocate (just as viv said). If it helps, write down "head MRI" and hand it to her. When she asks you what it is you will have an opening to talk about it. That way you won't forget and won't feel like you are being pushy.

You are your own best advocate when it comes to your health. No matter how much you like the doctor, you have to be willing to ask for what you need. I'd suggest making a list of the tests you would like her to consider, along with your symptoms, questions, etc.
Let us know how things go tomorrow! Good luck.
