A rogue week of anxiety like the one you experienced? No, that is not normal. What happened shortly before that "6 days of hell?" Did you change your diet? Did you get into an argument? Did you experience a huge loss of some kind? Did your current living circumstances change? Lots of variables can cause you to experience a week of anxiety.

For example, I had a week of straight anxiety at a previous job. I had another week of anxiety when there was a heatwave (my asthma gets triggered by high humidity levels or low humidity levels). Finally, I had a week of anxiety when my monthly cycle lasted 3 weeks thanks to perimenopause. So, all kinds of variables can cause a week's worth of weird anxiety.

So, something or someone, your bad eating/sleeping habits, your relationships, or even any health conditions that you have, could have easily triggered your 6 days of scary anxiety. Did you know exercise can trigger anxiety-like symptoms? Who knew? But it does for some people. Or, even your medication combinations can trigger it; so can vitamin and mineral deficiencies; bad diet for week; drinking alcohol and not eating can trigger anxiety.

Something will always cause anxiety to happen. Anxiety attacks won't happen idiopathically, (unknown cause) and any doctor who tells you that is true, is being lazy and apathetic.
