If I ever even got that much money I'd focus on dealing with the most important matters in life such as my health and possibly even going incognito and get myself a different identity and be in or set up something like a private witness protection kind of thing for myself. Sorry, but I would get really paranoid about it and worry for my safety and survival first. The trust issues I have may even greatly increase and unless somehow I can make a deal that I can pay those taxes to the government and that they agree to keep all information classified and confidential about my true identity as the lottery winner as I wouldn't owe them anything else and I feel I should not let anyone else know that I do NOT Have to about it that I am the one that actually won.
With that kind of substantial financial resource I might even need something like a fallout shelter built and constructed like it had been for VIPs so I can take refuge should the shit ever hits the fan, as I would take no fucking chances because of the current state of the world, as who really knows for certain? Because the end could just happen sometime in the future and I rather be as prepared as possible and necessary with that substantial kind of financial resource than just spend it all things that would just get me carried away and wasting my time and as well as my health on.
Like the "Joker" once said about all that big pile of money "Everything Burns", so I say forget about all the material stuff such as blingbling, mansions, fancy cars, private jets, etc. in this world and I'd prioritized everything that I absolutely need them to survive. Sure I suppose I could have fun and travel once in a while but this world has become really messy right now, it's not really that safe any more.
So if that's the case I'd only use the money to keep myself alive as long as I can but if I help others in need which I probably should to put that money to good use and to prove that I'm not just another rich snob and selfish son of a bitch, but then I need to do it discreetly and not be detected on someone's radar that I've become another rich guy by merely just winning the lottery. All just to make myself useful for once, and I know having that amount of money does not immediately fix and correct any and all problems I am having or experiencing or will eventually have. But it would more or less completely resolve my worries and fears of ever ending up completely flat broke and homeless at least by retirement age.1
