I can't help you, but I can tell you that if you hold out for a couple of decades, you'll eventually stop worrying about it.

One day, you'll realize that you wake up in pain and suffer through most of the day; that you are constantly annoyed that young people think they're the first and only people to discover or experience things that you've seen people discover and experience countless times - but you are also hopelessly jaded and desperately envious of their naivety and ability to be passionate about something other than injustice. That despite fighting for decades to improve the world, and believing in some cosmic karma, you see evil people succeed over, and over, and have a deep recognition that the world is fucked and getting more fucked with every dollar. When this time comes, the Void will become appealing: a rest and relief from pain and suffering. One day, you will realize that you no longer lay awake at night anxiously fretting about not being alive, but are rather looking forward to it.

Hang in there, man.
