Maybe I'm wrong but it sounds to me as Perfectionism.
I also suffer of this. Strong traits the doctor said.
I began by accepting my own boundaries and that there wasn't a way for me to be perfect. Of course, you also have to take into account your qualities. A person is full with both. Learning to be less severe and strictic with yourself, you will be able to appreciate the good in people and having compassion for their faults.

In my case, it was on the contrary. I used to be less severe with others than with myself.

What I'm gonna tell you now is only an idea, ok.
Have you ever considered the posibility that what you see in people that annoy you so badly could be a réflex of the things you don't like in yourself and you don't want to see them?
