Just how much do you weigh? How did you lose that much weight if you're lying in bed all the time? Why are you checking your blood pressure all the time? Why do you keep going to the ER instead of getting a regular doctor who knows you? My point being, you're thinking yourself into a panic over and over but you're not doing anything about the issues you have that would be a consistent plan of treatment -- ERs just evaluate you as quickly as possible but then you're supposed to go to your doctor, not keep using the ER. That's not what it's for. If you're in bed all the time, for example, you'll never get over your back problems. I don't know if you ever needed that back surgery or not, I wasn't there, but for most people it's an unnecessary surgery that is hard to recover from, but you can't do it lying down all the time -- you gotta move to keep the back loose. So your main problem is, you're too anxious to get proper treatment. All of us anxious people are like that to some extent. To overcome it, you need to get into therapy with a psychologist who specializes in anxiety treatment, if it's this bad you might need a psychiatrist for medication, and you need an exercise program from a physical therapist to get you moving again.
