Hey Op, my mom got diagnosed with a few months ago pancreatic cancer and my dad got diagnosed with prostate cancer a couple weeks ago. The way I've been dealing with it by appreciating the time that I do have with them, and at the same time trying to make sure I have a life worth living with and without them.
I would advise you to just make sure your life is in order so that they know you'll be okay without them. That's the most any parent could hope for, I imagine.
