Histamine and Panic

*trigger warning* Hello, I am on here because I’m needing some kind words or even someone to say they have experienced this. About 4.5 months ago I had a weird sensation come over me and my heart rate spiked. Well to make this nice and short I went to urgent care and I was “fine” well the next night I started having the jolts awake. Where you are almost asleep then bam jolted awake. Then panic set in. It last in a constant anxious panic state for weeks. Developed POTS like symptoms and severe orthostatic intolerance which usually ends up with hypotension. I moved out of my house and moved in to a tiny house that’s not finished. Adding to the “bucket”. Well, I wasn’t able to eat much and I wasn’t really watching what I was eating. Just avoiding large amounts of dish as they made me shaky. Certain foods did too. I never could find a reason why. They didn’t have things in common that I could tell (it was probably histamine). Well, I was managing my new POTS symptoms and then 2-3 days ago. I woke up with that panic feeling again. I couldn’t stop. At this point I feel like I’m actually going crazy obsessive thoughts, intrusive thoughts, constant adrenaline making me feel like I’m going to act out crazy. I ate some chicken my brother made me. It was fresh from the store and only had salt because I was aware of histamines at this point and figured my bucket was full. I felt betterish as the day went along….. Fast forward to later that night….I got a call at 5:00pm that my brother in law committed. He was gone. More added to the bucket and deregulated nervous system. I didn’t eat anything but that chicken that day and I went into a fasting state and the panic didn’t return. I woke up that next morning. Without eating it returned almost as soon as I woke up. It’s been a couple days constant panic, feelings of doom, scared, feeling like I’m developing a psychiatric issue. Am I going crazy or is it histamine? Has anyone felt constantly panicked? Most of the time I think people’s comes whenever they eat histamine. I have been eating little to nothing and very low histamine and feel almost worse. I want to take DAO (I ordered it) but it can lower blood pressure which I don’t need. I want to add that I’ve been taking a good multivitamin, digestive enzymes and turmeric for inflammation. I feel like I’m about to have a psychiatric break. I have a doctor appointment Monday but they always just listen and don’t offer suggestions. Plus I don’t truly believe anyone is well versed in this and I’m afraid they will just offer me medicine and tell me it’s anxiety. Help.
