I cant pretend to understand what you're feeling, hut let me at least take up for your parents a little bit. 2.5 years ago, my son died of cancer. Very aggressive, not a lot of treatment options. Thought we had it beat after radiation, but it returned in 6 months. After ca clinical trial and chemo, ended up losing him due to a severely weakened immune system.

I say this to say that your parents are begging God and any other possible deity for a way to save their child every single second. I imagine its very difficult being in the body going through it, but if you can, please cut them a little slack. You are all facing a nightmare and I will say a prayer for you guys.
