Oh yeah, I'm a recovering perfectionist and just like an alcoholic I'll always be in recovery. It's too easy to slip back into old patterns. Black and white thinking is a cognitive distortion that is a hallmark of perfectionism, and not much is more black and white than JWs.
I highly recommend the book "Happier" by Tal-Ben Shahar. That book really saved me from a lot of my perfectionism and helped me change my perception. I read a few others on the subject, but that one always stood out to me.
You, as you are right now, are enough. JWs teach you that you're never enough. I personally think that the whole concept of God and the Bible was created to control humans, something that perfectionism is all about (control), and since shedding perfectionism I've also shed the JW cult and the need for the Bible/God too.
