So I’ve been diagnosed with panic disorder since I was 5 years old. I was prescribed my first medication (zoloft) at 8 years old and have been medicated since (now I’m on cymbalta and lamictal). A majority of my childhood was spent having panic attacks in school and at home. As I reflect on my life, I’ve noticed this trend when it comes to my anxiety. 
When I was 5-14, I would have an extreme fear of throwing up. 100% of my panic attacks, which were multiple times a week, were because I was afraid I was going to throw up. As I grew older, that fear slowly faded and I didn’t have anything to panic about, until my brain hyper-fixated on a different fear to latch to. I got into my first relationship in high school and all that anxious energy transferred from the fear of being sick to the fear of being abandoned by my boyfriend. I would have panic attacks all the time about him leaving me or hurting me. After that relationship ended, when I was around 19-20 I developed this extreme fear of my younger sisters getting hurt or kidnapped. This was when my anxiety was at its all time high. I would spend everyday worrying about where they were, who they were with, if their phones were on, etc. i would even get anxious when they were at school or practice. When they wouldn’t answer their phones, I would call their friends. It got so bad and toxic. I would have the worst panic attacks every night terrified they were hurt. It genuinely felt like they were. 
Then covid hit, and they couldn’t leave the house, so that fear faded. 
During quarantine, I became very fascinated in spirituality and occult. I discovered my love for astrology, crystals, and mindfulness. Since I was home all the time, I used social media as a means to learn more. If you are familiar with this online community, you know that there is a LOT of fear mongering depending on the area of spirituality. Like Judgement day, being spiritually attacked, crazy conspiracy theories about horrible people running the world, etc. my anxiety started to hyper fixate on these conspiracy theories of human trafficking and and the “cabal”. Even though I truly didn’t believe in it, the fear of it possibly being true scared me so much. Every night I would be terrified of being spiritually attacked. I would stay up all night in complete states of fear thinking I would get hurt by some ghost. I started realizing OCD like symptoms of intrusive thoughts and thinking compulsions I’d do after I’d have an intrusive thought. And even thought I knew it was irrational, my anxiety would still panic over it. Then, when I overcame that fear (although I still sometimes get intrusive thoughts about it), I started having a fear of going “crazy”. 
Throughout the years, my panic attacks would revolve over these different themes and ONLY those themes. 
I am doing so much better now. I still get panic attacks and intrusive thoughts of the spiritual and going crazy theme but I am able to rationalize with myself to overcome them. Does anyone else have any similar experiences?
