Where to get help if your vaccine injured

I have been severely injured from the covid vaccine. I was once a mid 40 year old male who exercised daily, golfed 4 times a week and skied 3 times a week. Now I am unable to do any of those things. It started after I took a covid shot. I did not recieve any shots until my doctor convinced in December of 2021. Well after things were over and I was in excellent health. Unfortunately I took his advice and went to get it. I did. It recieve the first or second shot. I was administered one of the phizer boosters. I immediately developed a rash all over my body and felt like I was dying. I went back to the doctor and they tried to convince me that it was normal. I did not believe them. 3 months after the shot I passed put for the first time and was in the hospital for 4 days. Left with no answers and once again told the vaccine was not the cause. As time progressed I had less and less energy and when I would try to exercise I would have episodes where my heart rate would increase rapidly and I would constantly shake. They tried to tell me I was having seizures and once again told the vaccine did not do this. As time progressed I slowly became unable to do physical activity and work. I constantly feel that I'm stuck on a airplane with so much pressure in my head and you can feel every heart beat in your head. I have to remain as calm as possible or my heart will start pounding and it feels like all the blood is rushing to my head and I'm going to pass out. I have been to neurologist and cardiologist but they only want to do the bare minimum so thwy can't find anything wrong and say it's not their problem. The last test I had was a tilt table test in which I passed out during and I was told by the cardiologist to stay hydrated and wear compression socks. As someone who was an athlete and feels like he's fighting for his life at this moment in time I have been failed by the same doctors who told a healthy individual to take something that they had no idea what it would do to them. And when it completely destroyed my life, they want nothing to do with you or point you in any direction for help. I am asking if anyone know anything of where I can go to get help. I'm fighting for everything I have and I'm tired of doors being shut in my face when I'm begging for help. Thank you
