It's not really a lot of money, but it is a non-trivial management problem you'd have to spend more time than you think responding to- and at an opportunity cost against things that provide belonging, satisfaction, hope, and joy. With these new obligations, you need to manage them so that you can focus on those other good things.

Get it managed, out of cash, and get it planned for and pay yourself your old salary with a small raise for a bit. Be sober for a while. Avoid sex workers. Rent a supercar before buying one. Use a personal trainer to get fit. your job is "managing investments" to anyone who asks. Luxury is mostly symbolic. Family and friends are both free and irreplacable. Privacy and mobility are usually worth it.

It's not something you are, it's just something you manage now. There's a great quote from the BlueBottle coffee guys, "money in hand, not in heart" or somesuch. How to extract value from a big pile of cash is a challenging question that really smart wealth managers get paid stupidly well to solve, and there's zero reason why you should think you can do it without investing in some education. Take some time to grieve the attachments it has evaporated.

You're just you with a new and peculiar set of problems. Good luck.

(I don't have that money, but I've known it most of my life, and within my means I've just learned to do the things that people who can have anything in the world choose to do. they're pretty good.)
