I don't really struggle with panic attacks anymore, but I go from being fine to not in seconds. To me, it took time to get there. To him, it looks like it came out of nowhere. I basically just start word vomiting lol. We have had many arguments. My husband and I are both Christians, but I have made it clear that I do not want any shame from anyone. I shame myself enough as it is. My husband is very rational, and anxiety is very hard for him to understand. He can clearly think through things that I just can't. I feel for you. It takes a lot of patience, but he will learn. My husband has made a lot of progress, and he is always trying to learn. It does get better!
My husband and I will be married for three years in January. Our first year was DEFINITELY the hardest.
