You can't choose what does and doesn't annoy you. If she annoys you, she annoys you. But you feeling annoyed is your problem, not hers. You have no right to communicate to her that you find her annoying. She has a right to be at the center, same as you. Keep your feelings to yourself.

Roll your eyes all you want, but understand that others will regard you as immature for doing that.

It sounds like those around you are finding you to be the annoying one with all your "venting." Venting is not a right. Dressing as one wishes is.
