Trust me, as someone with actual LADA (slow-onset autoimmune diabetes Type 1 starting in middle-age), it can also be challenging to find others like myself; there aren't that many of us. I'm not yet on insulin, but I'm not insulin resistant. I didn't get diagnosed in DKA, but rather from routine labwork including a metabolic panel (although it did explain some symptoms I was experiencing).
Type 1 is Type 1, although all of us are quite different in presentation, management, etc. The only real difference I see in the medical and scientific literature about why LADA is sometimes given a different label is due to the presentation: slow-onset autoimmune diabetes, most often happening in adulthood, and that doesn't always require immediate treatment with insulin (even though it is now becoming a best practice in the US to treat LADA with insulin from diagnosis). Ultimately, it's still autoimmune diabetes, although I strongly suspect there are many types of autoimmune diabetes (i.e., resulting from susceptibility through different genetic sequences, different viral or environmental triggers, and involving different antigen responses).
Diagnosis in childhood of course has its own challenges, but so does Type 1 diabetes in adulthood. My youngest brother was diagnosed at 21, and my grandmother and great-grandmother both were insulin dependent diabetics (and almost certainly "LADA" presentation in adulthood). But that is the entire personal experience I have with real-world, Type 1 diabetics like myself. I have met one colleague with classic rapid-onset adult Type 1, and I've met many Type 1s online in this community and some others. But even online, there are very few of us classic LADA types. So it's always challenging to find people to talk to with experience similar to mine.
Maybe the real takeaway is that classifying diabetics is always problematic. For every "typical" Type 2, there are probably thirty or forty who are not typical. Even two Type 1s diagnosed at 5 will often be very different in presentation and treatment (just read what our parents of diabetic members have to say about helping their children!). Although I've got the slow-burn autoimmune type of adult-onset T1, I run into more people here and elsewhere who were diagnosed in DKA. Ultimately speaking, we have very similar sets of symptoms, experiences, and management tools to deal with. We have far more in common with each other than we have that separates us.
