Agree. I've always regarded psych diagnosis as an explanatory story. Sometimes useful, sometimes not. And always changing. Took care when my daughter was young to avoid diagnosis for her, as those available at the time - BPD, ODD - were not useful. Now, same as for me, she's clearly recognisable as autistic. For her (born in 80s) as for me (born in 50s), when we were little that would not have been identified. My frustrated & furious train-obsessed older brother, yes (tho in those days it was attributed to bad parenting & they medicated my lonely & unsupported mother instead); but me, no way. I like to hold my concepts lightly.
