RE what you are missing -- from your other comments I feel you haven't done much prior reading on the topic. There's lots out there, so go for it!
There has been lots and lots of writing on the phenomenology of mental illness and modern mental health culture. There is lots to not like: for instance it tends to encourage excessive rumination and negative feedback loops and over-identification with these designations, as you say. This is why I prefer to think of my diagnoses as models -- they are approximate descriptions of my behavior, and the treatments prescribed are also approximations, and it's up to me to use these as tools to improve my life. But you might enjoy reading some prior art on the topic
But in any case, if the tools aren't useful, then discard them -- I was diagnosed with PTSD in my early 20s, and at the time it was a tremendously helpful and eye-opening -- it hadn't occurred to me that the violence I experienced was impacting me so many years later, but when someone pointed it out to me, I was able to adjust the ways I related to myself and other people, and for the most part, my symptoms are in remission today. I no longer think of myself as "someone with PTSD" -- it's no longer a helpful lens through which I can understand myself
