why no diagnosis?

Hi .I am really desperate.I dont know if anyone has any ideas , suggestions , comments. I am 31 years old . I have long history of anorexia and bulimia and heroin and cocaine addiction.Have been clean many years ( a couple relapses). Started getting chest pain 8 years ago. Its got progressively worse. Pain everyday , sometimes dull , heavy or full on. dizziness , severe coldness limbs . Anyway was walking about and functioning more or less.But 2 weeks ago suddenly feel so dizzy I need to hold the wall if I try to walk , spinning ut, so weak havent been able to have a shower or walk from one room to another. It comes in waves , then I get moments of feeling o.k again and then really weak . heart feels so tired.And the chest pain continues.sometimes my pulse feels irregular but mostly just very weak and slow 45- 60 bpm. my blood preassure is generally 69 / 90 but has dropped to 45/85. I have difficulty eating  like I am just too weak . and I love food but I cant even stand up in the kitchen to cook . talking tires me out. Anyway over the years I have had ekg, 24 hour EKG, stress EKG , Echo , BNP 2 months ago was 48 and all other tests normal except some mitral valve regurgitation. I had part one of a myocardial profusion scan but had such a severe reaction to the radioactive tracer ,I thought I was going to die .And I think I am dying now so if I did the second part I think it would just tip me over. I am not generally very short of breath but the other day I was gasping and it felt like my heart was stopping.The doctors say there is nothing wrong with me , one doctor said he thought my chest pain was due to low blood preassure but does it cause such severe symptoms . I am told its anxiety.! I am so at the end of my tether , so desperate. If they could give me a diagnosis at least I could feel some control of the situation but at the moment I am dying and no doctor listens or believes me. I am holding on for dear life . I hope I get some help soon.

Sorry for your problems.  All the tests can be negative, but you may still experience angina (pain for lack of blood flow to the heart), and the condition goes undisclosed if the problem are the heart's micro vessels (very small). The micro vessel occlusions are often and usually not shown by the a stress EKG with perfusion (but you didn't complete) so there is a possibility there is coronary occlusions.  

Have you tried sublinqual nitro?  If you have angina, nitro will immediately provide relief as the vessels will dilate and provide a better blood supply to the heart tissues.

I haven't heard  low blood pressure causing chest pain, but anxiety (emotions) can/will constrict the vessels, and that can cause chest pain.
