For this group of people, the catalyst for the anxiety disorder to manifest is usually a trigger like extreme exhaustion (mental/emotional/physical) or sudden upheavals like a bereavement, illness, trauma, or the end of a relationship (separation). Sometimes anxiety doesn’t spring from one particular life event. For these people, it originates because they haven’t been looking after themselves properly (e.g., not eating right, not getting enough sleep, or consuming too much caffeine and alcohol). Poor diet and not getting the right amounts of key nutrients is a real trigger for many.
