@Roberta,
Hey Boida
I searched around the internet and couldn't find any Bellevue hospital services that were apt - tho they do have a contact us on this page
http://www.nyc.gov/html/hhc/html/contact/contact.shtml
which, if you scroll to the bottom of the pages there's a blue box which says Send A Message to the President of HHC
(course I don't know if that is the right hospital) - but it might be worth a shot asking if there is something that can be done to assist you maybe financially... or otherwise.
it brings up this page and you can write up to 150 words as an enquiry giving your email as a contact point
http://www.nyc.gov/html/mail/html/mailhhc.html
may not be useful coz I understand about the having to wait around for hospital cars to be available... but, nothing gained, nothing ventured.... $40 .... highway robbery!
Glad you are doing so well, such welcome news goil, and looking forward to pics or descripts of pics... fascinated by the art therapy - it has given you so much peace, focus FAB.
