I have been there. The mouse was not any larger than my hand, however for some reason it frighten the hell out of me. But there is something which you can begin using now for the better of your own fear.
In many instances a compulsive fear of mice or rats is a socially stimulated conditioned response, combined with (and originated in) the startle reaction (an answer to an unexpected stimulus) which is common in many animals, including humans
It’s not deemed a true disorder. Yet that will not help you in the event you fear mice and rats!
The Dark Death
I think much of our fears can result from history. Certainly in Europe we have all learnt about the Black Death. That rats and mice carry disease and death. With EFT you can easily master this emotional fear.
Even though I feel all mice carry disease and death… Even though I believe I’ll die because I have rats in my home…
Often something will happen to you, which will cause you to have a significant emotional response to rats and mice.
1 thing I remember was the movie, The Secret of Nimh. That was enough to make me concealed and hate vermin full stop. As a kid you just learn things from your parents, television and the movies without even knowing it.
