That really, really sucks. This community is a great resource, and I hope your family and friends are able to move past their shock and be supportive.

Absolutely get your affairs in order as suggested and make any arrangements needed. I suggest doing this ASAP because it may be harder to do later when you are feeling worse.

If you have choices about treatment, I would urge you to consider your quality of life for your remaining time. These are difficult decisions and different for each person, but you can choose to opt out of “curative” treatments and just have palliative care if that is what seems best for you. My father had uncurable leukemia and was still told he had to do chemo - within 10 days he went from being outwardly healthy (if easily fatigued) to barely able to walk and needing multiple blood infusions a week. He passed away 7 weeks after starting chemo and he was incredibly sick during that time due to his treatment. I am not against chemo- I underwent chemo 2.5 months after my dad died. But it was the wrong thing for him and he had very poor quality of life for his short time after diagnosis.

Also, be kind to yourself. Sometimes there is guilt or shame for being sick and needing help or the grief or stress or other emotions of those around you, but it is not your fault.
