Looking for Long Covid Doctors or Clinic in New Jersey

I am looking for either Doctors or a Clinic in New Jersey for Long Covid. I found one in Philly but it is 90 minutes away. I have been to 3 doctors and when I begin discussions, they have a strange look on their faces and try to blame my symptoms on my eating habits, allergies or lack of exercise. I am tired of being treated like a child with no understanding of my own body. Thank You in advance!
