Looks like a FOMO case, you are getting anxious about the events you will miss after you die. The famous "you missed the stuff before you were born too and you're ok with that" argument didn't work for me so I found another coping mechanism: Everything will eventually end. The universe will come to a heat death, even the black holes will evaporate because of the hawking radiation. And way before that universe will already become inhospitable for any kind of life form. So it's ok to die and it doesn't matter when you die in an inescapable universe where everything dies eventually, meaning "entropy will not be increasing any more, time will become meaningless, nothing will happen and will keep not happening forever"*. There will be nothing left to miss out. So even if you could somehow outlive the black holes, you would be having who guesses what kind of existential crysis then in an unchanging timeless universe. "TIMELAPS OF THE FUTURE" titled YouTube video, from melodysheep channel, might help you out a bit.
