Hard to know without more detail, but if your boss is a "fear biter", you should be looking hard for a new job. In the meantime, one (unpleasant) strategy that has worked for me in the past is to start adoring them at every possible opportunity. This can't be snarky--you have to make it seem authentic. Also, check out on trying to get anything done. Just go with the flow, don't go out of your way to fix things. No way to live, of course, so work on that next job.
