Wow - you've got quite a few treatments under your belt already. You'll be finished with them in no time. When my mom was getting radiation treatments, her doctor suggested getting an Aloe plant and using the Aloe directly from the plant to put on any affected areas and it helped her a lot.
It's natural to be concerned about the money aspect of all this, but try not to dwell on it. The hospital is working with you on it and as long as you continue to make small payments, you should be fine. Sure, they'd love you to pay the whole thing and get a discount, but they know that's just impossible for most people.
The saying my Mom liked was "If you want to make God laugh, tell Him your plans." :huggy:
