Anxiety about my health is ruining my life

Ok so this year I've been diagnosed with an Anxiety disorder. I've probably had it for a long time but I was scared to go to the doctor for years so it went untreated. I had two bad episodes which landed me in the emergency room twice in a week which led to many many Dr. vists which led to my family doctor, internal medicine doctor, and cardiologists all deciding I have an anxiety/panic disorder. As I saw the doctors more during these tests I became more and more convinced I had different illnesses. Every test we run seems to show up normal. I've had a chest CT scan, two echocardiograms, chest x-ray, stress test, 24 hour monitor, many EKGs, ultrasound of abdomen, ultrasound of legs, HIDA scan, and more.

The medical bills are running me broke but thank God I have insurance.

The thing is even now I don't feel okay and I have convinced myself I need a brain scan.

I want to stop living like this. The only thing I enjoyed in life was traveling and seeing new parts of the world and now I can't even go anywhere cause I'm afraid I will be too far from my doctors. The last trip I went on resulted in emergency room visit and I couldn't do anything but hyperventilate in bed the whole time.

I don't think anyone in my family understands how I feel or what I'm going through. I'm ruining their lives by even being around them. My husband tells me no matter what I'm going to be okay and he is trying to be supportive but he really doesn't understand how I feel.

Is there anyone on this sub dealing with these issues and can you give me advice? Please.
