All of this isn't really much help in how to cope with bad stuff in the long run, but small bits of insight that come in handy in my own personal Owners Manual...
But there is one thing you said that does help in learning how to cope with bad stuff:

I've realized how incredibly privileged I've been so far.
That's called counting your blessings. Gratitude. Thankfulness. What do I have in my hand? That is an empowering way to cope. To take stock and see that it's not so bad. Things can even be good in spite of some really bad stuff.

Thanks for the reminder.
