Full support from here ... I went through all 35 radiation sessions on my own - i.e. either getting support drivers from the Cancer Society which the hospital referred me to, and days when I was not able to have volunteer drivers, I have to arrange for cabs (Uber was not around those days/years!).
Good that you have roommates to reach out to, and at same time - perhaps the hospital that you are getting treatments from may be able to assist and refer you to a program.
All the best - take care !!
