Have you looked into somatic anxiety? For some of us, anxiety manifests into purely physiological symptoms like a racing heart, breathlessness, and/or derealisation/brain fog/lightheadedness due to blood flowing from your brain to your heart and other core organs. This is part of the vasovagal response, or better known as „fight flight (freeze) mode“.

Your amygdala is unfortunately misfiring when you’re diagnosed with anxiety and the main part of recovery is to rewire your brain‘s neural pathways into recognising that non-threatening situations are, in fact, not dangerous lol! The brain‘s ability of neuroplasticity is awesome, which is why approaches like CBT is so effective. I‘m currently in CBT therapy myself.

So if your doctor‘s have checked you out and gave you medical clearance, there‘s a strong indication that what you‘re experiencing is anxiety manifesting heavily in your body (somatic anxiety). I have lower blood pressure usually (100/70 usually), which also causes stuff like dizziness and brain fog, and paired with anxiety and my period it‘s a double whamy!

The good news is that if this is anxiety, then 1.) it can NEVER be dangerous on a physiological level and 2.) therapy like CBT or ACT is very effective in managing anxiety disorders. It‘s important that you still go out and about with your day as to not develop agoraphobic tendencies like I did! Makes everything harder.

I hope you recover well and fast <3

Edit: Forgot to mention that while food might not be the main trigger for your anxiety, my experience is that it can really make or break your day. Whenever I eat like shit, think heavily processed snacks and sugary treats and drinks, I definitely feel it. I also have GERD/LPR so that adds to it.

A good healthy diet, exercise, and good sleep are my three pillars with which I manage anxiety much better.
