Just to give you an idea of me. I'm 30, female, only a few pounds overweight, suffer with depression and anxiety. I have Hypothyroidism, but it is within normal range and I'm on 50mcg of Eltroxin for it. I don't drink or smoke, and I have a pretty inactive lifestyle as I work from home, so I'm on the computer most of the day.

Now, last few days have been awful. I keep getting a chest tightness and throat tightness, like it's full up and I need to let something out. I'm also getting little pinching pains in my arm, that seems to catch a nerve in my thumb or little finger. It's not as bad today, but still comes every so often. 

I was at my doctor yesterday, he examined me with a stethoscope chest and back, and took my blood pressure monitor. All was normal, he said it was my anxiety. I was also at the doctor a week before that, had a 24hr Blood Pressure monitor as well, all normal.

Is it a stroke? heart attack? Pulmonary embolism? blood clot? I feel like I'm going insane, it's distressing and ruining my day, causing me to just want to go to bed, as it is only ever relieved when I have a nap or wake up in the morning, and it gets worse after I eat. I'm really upset and crying all the time. What is wrong with me? Am I dying? I feel so scared.
