Hi Fluery,
Do you know WHY you have this fear?
I had/have it (to much lesser extent),and I know it
is because my parents would go crazy if I made a
mistake,so I became afraid of mistakes in later life.
The way I reduced it by large amount was reverse
psychology,i.e., to DELIBERATELY make mistakes,and seeing that the world did not crash
around me! I started with writing,something like
ThiS, anD tHis, and when I did make a mistake,I
would score right down whole of page----------------
get it?

. You could also not make bed CORRECTLY, wooooo! Not wash 1 arm,not do ironing Correctly, get it? You can make up any
number of things,till mind gets used to catastrophe
of not being perfect.
Kind Regards,
BLUEDOVE
