I was duped into believing I needed an SSRI and later a BENZO to relieve my anxiety. I weaned myself off of both after I did a lot of research to learn that the root cause of anxiety is mostly nutritional.
8 Nutrient Deficiencies That Cause Depression and Anxiety - Victoria Albina
For me personally, I was low in B, D, Iron, and Magnesium. My anxiety spikes when one or multiple of these gets low. Also, thyroid disease (which I have) causes anxiety and depression as a side effect (both hyper and hypo).
I will never take an antidepressant or Benzo again for my anxiety. I notice that I have less panic attacks when I also avoid eating processed food and processed sugar. This is just my experience. But I hate doctors who think prescribing a pill with serious side effects is the answer. They'd rather do that then test for vitamin and mineral deficiency or thyroid disorders.
