Hi Everyone!

Quick backstory: on February 2nd I got an intense hot flash with spotty vision and not necessarily nausea but a gagging feeling. I had it all night and every day since then I have had those same episodes and they are becoming a lot more frequent. I have emetophobia which causes me to start to panic which only makes things worse. I decided to go to the doctor because it has got to the point where they are diminishing my quality of life because they are so often I can barely leave the house. When I went to the doctor my heart rate was 135 and my blood pressure was 140/77. My doctor immediately diagnosed it as anxiety and got me started on anxiety meds. I happily accepted them as at this point I was desperate to feel better. I have other symptoms too such as severe weight loss (I have always been tiny but am now down to 89 pounds as an 5’7 19 year old, extreme fatigue, hair loss, irregular menstrual cycle, and my appetite is very small. Due to these other symptoms he also did blood work to make sure my thyroid isn't causing this. My thyroid came back normal but my white blood count, neutrophils, lymphocytes, monocytes, neutro absolute, and CO2 all came back irregular. My doctor is now assuming I have an infection of some kind. I am wondering if the infection could be causing anxiety like symptoms and maybe I don't actually have anxiety? I am wondering this because I have never had anxiety like this at all. I often get nervous but never anything this severe and I have always been able to calm myself down. Also my normal triggers for me to be anxious are obvious to me. Now I am having panic attacks (what my doctor is calling it)  when I am just sitting in my room doing nothing. These consist of only physical symptoms too, my mind is never racing and I am never nervous about anything in general. But my heart starts pounding, my chest gets tight, I get super shaky, and I start gagging. I am doubting the diagnosis because I have nothing to be anxious about. I am in college but all my classes are online and this is my easiest semester of college so far. I hadn't had any tests up to when this started and nothing happened in my personal life to trigger the anxiety. I just don't know how such severe anxiety could start one day out of the blue like this. If anyone can please help it would be greatly appreciated!
