Hi Kellie,
I personally experienced all the classic symptoms of a heart attack many years ago, and like yourself it was eventually put down to a stress and anxiety reaction. I can only support your doctor's findings, but the question now is as to what it actually is that is causing the anxiety you are currently feeling. You may think that the answer to this question is obvious - it is surely your relationship which is causing your heart to race, but in believing this I feel that you would be absolutely incorrect. It is not what does or does not happen to us that causes your stress reaction, but what you are telling yourself about it. If you will only listen for a short time to the voices in your head which are constantly interpreting everything about your relationship in the most negative possible light, then I feel that you will have identified the true source of your problem, and therefore will hopefully now be closer to finding a solution. Now I am not saying that you are imagining everything and that your relationship is a perfect one and that you should from now on accept that you do not deserve any better treatment from him - quite the opposite is true. But if you continue to listen to these terribly negative highly critical voices with yourself then you are very likely to quickly conclude that everything is entirely your fault. I am telling you that this belief about yourself is false, and is not grounded in reality.
Basically instead of being forced to continually listen to this mental drivel or nonsense that your so called inner parent keeps dishing out to you (or is punishing you with), you need to more carefully examine everything it says in the light of reason, and provide whatever evidence you can to show it that it is talking utter nonsense. When the voice tells you that doing anything to improve matters between the two of you is only guaranteed to make matters much worse then present some evidence to the contrary by looking back at an earlier occasion in your life where your actions have made things significantly better for you. As soon as the voice tells you something which makes you feel powerless or destroys what feelings of self confidence remain, be ruthless in writing down evidence which can be used to make your case that at many times in your life you have made what turned out with hindsight to be an excellent decision, and that you have more than enough inner strength in order to face anything which life can throw at you with regard to forming and maintaining your closest relationships. Only in this manner do I feel that you will give yourself hope with the intention to break this vicious cycle of disempowering thoughts.
While I cannot read him directly and make sweeping predictions about how your relationship will progress (or not progress) over the coming months, I do believe that if you can somehow get on top of these voices within you that make you feel effectively powerless and without any hope, that this will then give you much more energy left over in reserve to deal with the real problems you encounter, rather than being constantly overloaded by anxieties and concerns which may have either only a partial basis or in some cases no basis in reality. Also this should go a long way towards bringing your heart's behaviour back to normal as an added bonus. Some of your relationship problems will be there for some time yet, but because you are now more in control over how you react to what is happening, you will now have a distinct advantage when it comes to dealing with each of them as they arise in a mature and rational manner. This can only be seen as being a positive omen for not only this relationship, but also for your overall health and happiness in the future at the same time. This is the right direction for you to head, whether or not he is also willing to take some degree of the responsibility for your relationship problems.
Love, Light and Healing,
