I have extreme panic attacks only at night, why?

So for the last few days, I have had chest pains, nausea, and body aches (That feel like a fever). Called up a doctor explained my symptoms told him my age and he ruled it out as a panic attack or anxiety. My mom checked my pressure and heart rate and everything was fine. I've noticed that I would start to panic at night and have these symptoms for the whole night until I fall asleep. This morning, I woke up with extreme body pain. It's hard to explain but the symptoms feel like covid in a sense. Im a little scared what should I do?
