Repairs for wheelchair and medical bed

I am not one to ask for anything. Insurance has denied my request for repairs on my wheelchair and medical bed. Currently my wheelchair needs the two motors repaired or replaced, because they are on their way out and slowly dying. Making a grinding noise and making it harder for my wheelchair to go from point A to point B. Four caster wheels need replacing, because they are bald and have no traction. The medical bed has a crack in the manifold which supplies air to every cylinder that allows me to have what we call “offloading“ which allows the bed to inflate and deflate allowing me to not have my skin breakdown and end up with a pressure wound. Because of the crack in the manifold it is making the air pump box work overtime which is draining  the box very slowly which will have to be replaced as well. I know it’s the holidays so I don’t expect anything. I would rather you give to your friends and family first before you were to give a penny to me. Anything that is raised just know that I truly and greatly appreciate your support. I know it’s a lot to raise, but the medical industry is pricey.
