Not a check in, and I don't have real anxiety, but it's the closest description to what I experience.

I've noticed that disagreement makes me scared as hell. I was involved in some internet discussions lately and one that really...unnerved me the person and I agreed to disagree. She said she respected my opinion and left it at that. For some reason, even remembering that just twists me up internally.

For some reason I read this coldness and disgust between the lines of her post. I don't know if they're real, or if she really thought less of me for my fear on the subject. I'm almost certain of it and it terrified me. Not enough to change my views, that will take time if it happens at all. This feeling has happened before, too, when I suspect someone is angry with me, or disagrees with me. I don't know what it is I think is going to happen that's so terrible. I know I'm a little afraid of this user now because of our disagreement. Again, it's irrational, but so ingrained I can't seem to think my way out of it.
