Rant: T1 misdiagnosed as T2

About a month ago I was diagnosed with T2 based on my A1C of 9.6 and a fasting BG of 331. Today, I got the results of a blood test back and had elevated GAD (40, if that makes a difference). I'm seeing my endo tomorrow, but I think we already know this means that I have T1. I had been taking metformin, eating a keto diet, and was keeping my BS well within range in the last month.

I'm devastated. My mom has T1. I alternate between denial and feeling like my nightmares are coming true. I'm single, live alone, and work in a high stress job. I can't leave the job because I don't want to lose insurance, but I don't know how I can keep up with this diagnosis. If I start insulin, I will be scared of living alone - I've seen my mom go through too many terrible episodes. I wanted to eventually get married and have children and I feel like all of that is suddenly a pipe dream.

I'm not looking for medical advice. But if anyone has any words of encouragement, I'd appreciate them.
