Trying to raise funds to get Joseph to NYC Clinic

My name is Renee and I am trying to raise funds to get my son Joseph seen and treated at the Mt. Sinai Clinic. He was diagnosed with Neurosarcoidosis in September of 2022. He was walking and able to take care of himself back then. He is now in a wheelchair and cannot take care of himself. This illness is rare and needs to be seen by someone who has experience. There is a clinic for Sarcodosis at Mt. Sinai in NYC. Looking for donations to get Joseph to NYC, to rent an Airbnb that does not have stairs since he cannot move his left side or leg, transportation while in NYC and costs of treatment at this clinic. Any help would be a godsend.
