It’s hard though. A key criteria (at least in the UK) how much it affects you day-to-day. My father probably has it and passed along a lot of guidance that I now recognise as coping mechanisms/symptom management strategies. Day to day I’ve got it in hand, it’s only when the big storms come that I struggle, and that doesn’t fit with the diagnostic approach.
It’s hard to not make them sound trivial, but you’ll see some of them in the memes that pass through here. Off the top of my head though:
When I write these they seem silly and trivial, but they help me a lot.
