@Sparkles1212 Absolutely 100%.
But I got blood tests done to check for deficiencies (Vitamin D, B12 and folate and also low ferritin that doesnt mean the NHS standard to be labelled a deficiency, but levels were also taken after a few weeks of supplementation so could have been even lower)
What I have found more important is macronutrients and diet. I had a poor diet and ate a LOT of sugar and refined carbs. Before my anxiety got really acute this year, I was starting to feel very bad after every time I ate. Like extreme fatigue to the point of intertia, even if I hadnt eaten loads. Magnesium has also made a very tangible difference, especially when my anxiety was bleeding into my dreams.
I ended up after some time cutting out gluten and dairy, at first I thought it was psychosomatic (I had developed a lot of irrational fear around food anyway) but recently tried to eat a mac and cheese and within half an hour had that same crushing fatigue and felt way more anxious than I had been that day. Annoyingly, having cut out both at the same time I can't definitively attribute my issues to either one but for now they are off the table.
Also really important is stabilising my blood sugar by eating regularly and focusing on balanced meals, not too carb heavy but definitely not no carb.
I will say though, making sure all these bases are covered absolutely help massively take away the intensity of anxiety. I have ADHD so its a struggle for me to keep up with these basics especially when before my anxiety skyrocketed I could make do with being lax.
But ultimately, when we are well we are able to deal with these without it causing anxiety, so the focus should be on getting help with your anxiety which involves therapy and understanding what a "hyperstimulated" or "disregulated" nervous system is, why it causes anxiety and how while it's really helpful to have the top down knowledge and skills from therapy, you also need to acknowledge the "bottom up" processes we need to engage in to calm our systems back down and feel safe. Breaking the loop is really important!
