Feeling stuck over panic and getting checked

I am trying to see if there are others like me. For the past 12 years, I’ve had crippling Anxiety that leads to intense panic attacks. I’ve been in and out of Ambulances and ER rooms and have called 911 several times. The panic is that intense. I can be just driving down the road and out of no where, BOOM! Hit by the anxiety bus. Most of the time it leads to me panicking, thinking I’m going to die or something is fatally wrong with me. The fear is so intense that I can only find a fraction of calmness by consistently checking my blood pressure, putting on a pulsometer and even checking my blood sugar until it passes. I’m not even a diabetic. I’m always having intrusive thoughts that doctors can’t even fix me. I’ve never met anyone else like me. I feel so scared sometimes that I’m going to loose my mind and that I’m going crazy and will end up in a straight jacket. Then I get another attack just thinking about that as well. Starting new medications freak me out too. If I experience ANY minor side effect, I immediately panic and freak out. I’m being so held back by this . This is a constant obsession that I can’t shake. It’s like I walk hand in hand with Anxiety and panic. Anyone else ever had these issues?

I have gotten maybe about 8 EKG’s within the lest 2 years? I’ve also gotten an echo done, and I got a heart monitor to track my heart over the course of maybe 2 weeks, back last year. Even though I have been to the emergency room so many times because of panic attacks that I thought were heart attacks, and went with a Cardiologist I still obsess and worry. I always think that I am going to develop some kind of heart problem after getting the tests done. Like if they’re just suddenly going to appear/my heart will suddenly have an issue. I especially get nervous when the pain is in the center of my chest + I get a tight feeling like I have pressure on my chest and can’t breathe completely. Please someone share their experience of how they controlled their health anxiety, especially if it’s related to this.

I went to internal medicine today, and i'm not perfectly healthy, My liver is a little bit fat, I have to lose weight so thats okay, also I have gallsand, which is not gallstone yet but it can become that if its not treated. Now im like these arent big problems but when i heard these I started to overthink and think about the worse that I will have gallstones cause the doctor said I have it cause it runs in my family(my mother/grandmother and uncle had it) and I just think that it wont go away, and even if i doesn I will be worried all year if it came back. Im just so afraid. Also they said I should go get a blood check, but I said i will hesitate now cause last time i almost fainted and felt horrible the whole day, and now i hear from people i know that they went and they felt sick and vomited there. But the overthinking comes from me thinking if these little symptoms I experienced which I thought its because of anxiety, was because of health issues then the other symptoms I experience sometimes (headache and lightheadedness) are there cause of another health issue, and im worrying about my health, im afraid of death, i keep imagining myself if they tell me that i have terminal illness or something really bad and i dont know how to handle it. Now i feel nausea and i would say its because of stress but i keep thinking that its because of the health issues I have...I don't know how to handle this fear, if you ask others or therapists, they will say "yeah everyone is afraid of death and suffering" or "Try to think about something else" and i wont pay for advices like this...
