Is it possible to be diagnosed with Type 1 diabetes mistakenly?

Hi, just received a letter from the hospital, where I was tested at, which confirms that I am a type 1 diabetic person.

Just wanted to ask whether it seems like I am type 1 given my circumstances.

Firstly, I am skinny and I am a teen and there are around 4 members in my family, who have diabetes. But, to my knowledge, they are all type 2 and they're skinny as well. However, they were diagnosed when they were middle aged. Given that my family nembers are type 2, shouldn't i be genetically prone to type 2?

I found out I was diabetic when I randomly asked my mother to test me on a glusose testing meter. I seriously never thought I was diabetic; I have some symptons, such as sleeping all the time, feeling thirsty etc. but I thought it was normal.

From what I've read around on the internet, some type 1s , diagnosed at a later age, were diagnosed after they went to hospital. I am not sure, whether it was because I discovered it super early, but I never felt affected in anyway that could threaten my life. My blood sugar, when I first tested it was only around 9.3 and it went down to 5.8, once, after a day of exercising.

I pretty much thought that being type 1 without taking insulin was life threatening. I don't seem to be very affected thus far but if I am diagnosed as type 1, I will probably have to take injections or the pump.

So, I am wondering whether it's possible that I am type 1 (could i be type 2) and I am just super lucky things haven't progessed to a dangerous stage. I don't know much about type 1 at all, in fact I am probably most familiar with type 2 given my mother has it.

Does anyone have a similar experience, where they don't feel so affected, but are diagnosed as type 1?
