Not all of that, but a whole lot of it is from being raised in... the American version of a Christian household.

These are the kind of parents who will spy on their kids, catch them masturbating, and then punish them harshly, tie it directly into their moral/spiritual validity as a person.

Puritanism is very much still alive and well.

It produces uptight, broken, neurotic people with those control and anxiety issues you mentioned.
