Where does the swirl come from?

One possibi­lity is an early childhood experience that lacked affirma­tion or expression of loving feelings.

If one cannot ask for what one needs (as a child) then thinking and feeling are badly affected. So the individual is sometimes forced into a space of minimal agency where it is hard to negotiate daily life. This means not having  one's own voice, instead always hearing someone else's real or imagined usually critical words.

Someone else holds the initiative and this feels shameful, and so leads to the swirl experience.
