Depending on how much, I’d keep what I’d need to fix up the house and get it up to code (it was last remodeled in the 70’s), medical expenses (as three of my meds cost $1,000 a month EACH), and general living.
After that, I’d open a media store that rents and sells video games of all eras as well as media formats from Beta to 4K. Also offer repair services on site as you know older consoles and VCR’s are breaking down.
Then whatever’s left, start a fund to help struggling people with getting them placement, financial support, counseling, etc, with high priority for my LGBTQ siblings.
Depending on the amount, like Powerball, maybe use some of that influence in local politics. Really want the city to buy up these abandoned buildings and houses, use inmates to fix them up so they can learn skills like plumbing, electrical, etc to give them good jobs on the outside, then turn around and use those buildings as low income housing so families who work a decent paying job or two can actually afford to live in a home.
But that’s just me.
