Husband of Diabetic. How can I do better?

I apologize in advance for the long text. I haven't shared this info with anyone and appreciate the outlet.

In late February of this year, my wife was diagnosed with, what we were initially told was type 2 diabetes. She is 26 and I'm 29. Her initial A1C came back at 11.9 which scared the shit out of both of us. It also came at a pretty bad time as we were set to leave for a month long trip to Japan the following week. The doctor who diagnosed her literally told her to "take these pills and stay away from carbs."

I was horrified because she was given almost no education or nurturing regarding her diagnosis, and left the office in tears. We were able to see a doctor shortly before we left for Japan who upped her Metformin from 500mg/day to 1000mg/day and had us buy a bunch of Insulin for the trip. We were told that if she woke up with a fasting glucose of over a certain number, she would have to start injecting. She never reached that number, and shes been sitting in the low hundreds for the past few months. We were able to get on a program for diabetics called Livongo that was offered through my work. They gave us a great meter, and free strips when we need them. Very thankful for this as money isn't really showering us at the moment...

The type has not been confirmed to us yet, which I'm still not sure i fully understand. From what I'm gathering there are multiple types, but the main 2 are type 1 and 2. The second doctor we saw said he thought she was type 1. But we haven't had to inject her with insulin at all. Shes been on a steady 1000mg of Metformin daily, which has kept her numbers near 100. From what I'm gathering through my basic Luddite research, that is decent. She'll be having her labs tomorrow, to check her new A1C and determine what type she is.

Her spirits have been great. She has her days that are rough which are totally understandable. But for the most part she's positive and doing great. I have fully changed my diet and lifestyle alongside her. We have implemented moderate exercise into our daily lives. I have tried to be as reassuring as possible and maintain my health alongside her. We are adjusting to the new diet, getting skinnier, and staying positive.

I have broken down quite a few times away from her, because it kills me to think that the most important person in my life is sick. She has also noticed a few grey hairs sprouting up in my beard, probably from the late night reading that I've been doing on the topic.

The point: What can i do better? Please let me know if you have any advice as to what i can do better or be more supportive. If i have used improper terminology, please forgive me. I am new to all this, and I just want to be as supportive as i can be. Thank you folks in advance.
