Fight/flight reaction from childhood

[BlueCookieMonster]

So in therapy today, we hit upon the fact that my fear of messing up is related to abuse I suffered in childhood for messing up then (I’m sure you can imagine it wasn’t proportionate).

Does anyone have any tips/books on how to deal with such a learned response?

There is a documentary on free view channel 88 on Sunday at 9 called Resilience that deals with the impact of ACEs (adverse childhood experinces) and the effects of toxic stress that you might find interesting.
I have never seen it do can't vouch for it's content but have heard it talked about when I have been to seminars about infant attachment and it's highly regarded.
