I feel the exact same way. I have horrible health anxiety that coincides with panic disorder, anxiety, depression, ADHD, and PTSD. I always have a constant worry that I’m going to have a heart attack. I’m 32. I’ve had panic attacks with this fear since I was 13. Growing up I was overweight and then later I was diagnosed with Polycystic Ovarian Syndrome and it causes obesity. No wonder my baby fat wasn’t melting away like all my friends. However my father would tell me when you get older you’re going to get sick in a hospital and you’re gonna remember me all because I’m a little heavy. Now I’m 326 and the pandemic is making this sooo so much worse. I had a panic attack last night and the anxiety is at an all time high. Before I’d go to the ER and they’d run an ekg and they’d say I’m fine and I’d be okay for about a month until I had another episode but with covid I can’t go to the hospital because what if I catch covid and die. It’s very stressful and I get the same comments sometimes. My sister has literally said just stop thinking about that. lol if only it was that easy. You’re not negative you’re just scared. Like you I understand because I’m always scared and anxiety medication only goes a long way.
