My understanding of what happens when you enter the orbit of a black hole is that it appears you die instantly to outsiders, but on the inside it lasts forever for you because of the time dilation.
I would think that if you had enough supplies, the time dilation would extend beyond your lifespan and the outsiders, if they could see you, would see you age rapidly (to them) and then die long before being killed by intense gravity or radiation. Whatever, you’re dead no matter what. Don’t sit there waiting. Just pack a lot of alcohol and some fentanyl.
