How can someone overcome dyspnea, tiredness, chest pain, and tachycardia?

Hi doctor,

I was at the funeral service of a very close relative and did some walking around the building in the precession line until I sat down in my seat. I was emotionally upset and began crying, then got very short of breath for a while, and both arms went numb. My left arm was completely numb, and my right arm had a little more use of my hand, but neither arm would lift without dropping. I kept breathing in through my nose and out my mouth to get my breathing back to normal. Felt like I was going to pass out. After a few minutes, I was okay but still very weak. Then, I started having chest pain with tachycardia. ECG read abnormal, cannot rule out anterior infarct, age undetermined. I have not had any prior indication of heart problems before this. I have had dyspnea upon exertion and getting tired and winded during exercise for at least a few years. Just thought I was out of shape. The stress echo only showed some tricuspid and mitral valve regurgitation but was done without a definitive diagnosis. My test ended early due to fatigue and shortness of breath. I recently climbed four flights of stairs and headed to work, and my pulse was 160 bpm, and my O2 sats at 86 % at the end. Chest pain lasted ten days, constant and intense, before subsiding. Starting to feel as if I need to go to another health system because I am not getting real answers from my current care team. Kindly advice.
