Agreed, don't get hung up about the exact diagnosis, it doesn't really matter. Everything to do with help, benefits, best way forward and dealing with issues are specific to your circumstances not the exact "name of the beast".
Some people never get an exact, or correct diagnosis as it's not always possible until after death, it's all just a name not how your lives will progress.
The more specific you get the less people reply, the issues are common to us all, the diagnosis often isn't but we're all here to help each other as much as we can.
