I tend to get easily irritated when my anxiety is rearing its head. Mainly it annoys me when people talk, period. If they aren't talking about something I find very interesting then I just cringe at the words coming out of their mouth. My husband comes home every day and starts talking politics almost immediately. That is just too stressful a subject when I am anxious. He can tell when I am anxious b/c I won't look at him when he speaks and I just say "yeah, yes, and mmm hmm" over and over again. I know he is just being himself but when it is really bad I will just ask him to talk about something else b/c I am stressing over the conversation. He usually takes it really well as long as I act slightly interested. I agree that it is key to be polite. If I am short with him he gets irritated back. You aren't alone.
