Disheartening

I’m writing this lying down with tears on my eyes as i am about to be kicked out the hospital because i had to pay cash as momentum wouldn’t pay through my accident cover because they claim it’s unrelated.last year October i had an accident and went to the hospital,rehab and outpatient therapy till this year and self catherizing as i couldn’t pee like a normal person due to the accident,on Thursday the 5th i got sick throwing up and diarrhea,went to my normarl GP because i knew that i had day to day on my cover and i was okay with self medicating or going to the government hospital if need be, However on Monday i couldn’t pee at all, i tried self catherters but were coming back with discharge and my bladder was swollen.likely the next day i had an appointment with an Orthopedic to check the pain on my lower back and bladder he the then said i have an infection to my bladder because unfortunately since i’m using self catherters i am prone to these kind of infections and referred me to a physician to admit because it was bad and gone a day with peeing momentum declined to pay from the remaining balance of my cover because to them it’s unrelated to the accident and i’m failing how is it unrelated?will i be using these catherters if not for the accident? and opened me to a new whole world of infections, next time it might not be this what if i find out i have water on my spine coz i had an operation? will that be unrelated as well? or called medical.From the time i was admitted they’ve be dealing with this infection antibiotics-antibiotics and the nausea that comes with it. the diarrhea i have cured it at home on my own. I don’t know what they need from me to prove that this is related to the accident and complications that comes there after since i’m paralyzed.My family have coughed up almost every savings for December they had so i can be treated but they have nothing anymore.
