-- "You are making me tense."
-- "You are stressing me out!" is an informal/slang way to express the same idea.
-- "I feel tense when you _______ (shout, drive fast, do ____ , say _____ , etc.)." This is a good way to say it if you want to sound less judgemental. You can say this if you want to avoid or end an argument rather than start an argument :-)
