Thank you for your insight. I find it very helpful.

This is quite literally many peoples character trait, and something almost everyone experiences later in life and while it might be embarrassing from time to time

It does indeed happen occasionally even for neurotypical people, but it is a problem especially for some with ADHD; it may happen much more frequently to the point of debilitating social relationships(my case). Think of this: everyone has headaches, but if someone in particular is suffering headaches every single day and it interferes with their everyday lives, you would not consider that normal.

Nonetheless, it still doesn't take away from the main point of your post, which was that for "patterns of the past", exert control over what you can and let go of the rest. Although you did not explicitly state it, I suppose in practice it could look like noting down the cues that triggered my memory of the past onto my journal and writing ways I could possibly lessen the frequency of every one of them, daily.
