When You Cannot Deal with Perfectionism

One thing I have discovered is I am not far enough out of a doctrine of perfection to be in circumstances that remind me of the hurt it caused.  It's not far enough behind me.  It has been almost two years since I left an environment that equated perfection with pleasing God, that drilled their doctrine of works over and over.    Since then, I have been in similar circumstances; and every time, they lead to too much stress.  I find myself in that circumstance again.  Sometimes I just feel like saying, "I got away from that.  I don't want to go back."  Right now, I'm not sure how to deal with it.  I know God will give me answers.
