I am sorry to hear about the problems you are having for so long. No one here that I know of is medically trained, so we cannot and do not give medical advice on whether your condition is dangerous, for example.
This forum on MedHelp is focussed on Lyme Disease and related infections. You may want to try a different forum related to heart disease.
