I would probably go on a massive scavenge. Starting at my home, I would collect all my most valuable possessions, memories, photos, etc. Lots of paper for writing and drawing. Then I'd scavenge further and further out across the city, finding the things I'd need like food, large transport vehicles and fuel, generators to charge my electronics, spare electronics to store data. I'd find the houses of those I once knew, even if it takes months of searching, and collect photos and memorabilia of them. Boot up their electronics, collect data, photos, memories from them. All the while, drawing, sketching, writing. Recreating maps of the city, images of all the places. Animating on the computer. After a while, I might study some of the books from the naval base, drive a ferry to the mainland, to retrieve memories from one specific person. Locate government offices to track addresses and ease my search. Still drawing, writing, animating, collecting.
And across a period of years, animating memories. Recreating moments of my life with all the people I loved and missed. Making so much of it that I can forget some of my pieces and rediscover them later. Write dozens of novels, all the stories I've wanted to write and draw and dream. Collect and read hundreds of books.
Already, I have learned that I adapt well. I don't care when I am separated from the people I care about. I can bear solitude, though I of course prefer company. But my greatest regrets are always that I so easily let go. I stop caring about people, I forget why they meant so much to me. My greatest wish is that when I am separated from them, that I could be sad and miss them. And hopefully, after years of this rediscovery of myself and others, perhaps I can attain this perfect sadness and be at peace with myself.
