Hi I cant give specific feeback on this hospital. I have been to UCLA and Cleveland Clinic where the wait was so long for the appointment but what I did was call everyday to see if there was a cancelation and I got in a couple months early. I encourage you to do the same. Sometimes you have to just keep nudging them.
I am sorry about your family. It is hard when people dont understand. Could you find some information on the internet to try to educate them? Is there anyone who can help you with the items you need to get done?
