I would appreciate some answers about Women Heart Attacks Please?

Hi All. This may get a little long but I'll try to keep it as short as possible. Im a 31 year old woman, 5'4, and 150 pounds. Heart disease is huge in my family, both men and women. In fact, my sister was 29 when she had emergency surgery to replace her descending aorta and is living with a ascending aortic dissection rite now at the age of 32. I have gone to the ER several times for my own heart fears, racing heart beat, severe chest pain, shallow breathing. I was diagnosed with a severe panic disorder 5 years ago so I do know what that feels like and what Ive had for the past 3 days is not panic. I woke up 3 days ago severely dizzy, couldn't hardly stand. Following that I had diarrhea for the next 12 hours. I couldn't even keep water down. Thinking it was the flu, I rested and drank what I could. Then yesterday morning I woke up with chest pains on the left side of my rib cage, toward the top near my . It was more annoying then painful. This came and went all day yesterday, still dizzy, but the diarrhea had stopped. Today the chest pain has been where I said earlier, but has also been under my left , middle of my sternum, and over the top of my . My left arm has had some pain, and it tingles/numb like. When I get the waves of pain in my chest, I feel flush almost like ping out. Pain lasts 10-30 minutes then is gone again. The numbness feeling in my left arm hasn't really gone away tho. I don't have a BP machine at home but I did check my heart rate and if Im doing it correctly (count beats for 10 seconds then multiply by 10) my rate was 150. So if you are still with me, and reading this (I APPRECIATE IT DEARLY) what could all of this mean? Heart attack? Muscle strain? Any ideas? It does not hurt to take a deep breath, not heavy feeling in chest. I would have already gone to the ER but I just moved to a new state and do not have insurance set up yet. Any advice would be greatly appreciated!
