Okay, so there are two best possible worlds I am picturing right now.
In world 1, I live in the Valley. I move to a loft in a converted factory building, where I devote a healthy chunk of my vast living space to a messy studio. I bike to my new (but with same coworkers) job downtown when it's nice out. I have a bunch of friends I know and love, and we go out and do fun things together often. I feel safe. Town never changes much, but I find new things to do once in a while. I travel to NYC on weekends sometimes to see my family. I have a sculpture show during one of the open studio weekends at Eastworks, opening up my apartment to strangers; I am very charming and they are all complimentary. I meet other artists in the building and we commiserate. I decide to make a large number of items to sell at the nicer craft shows in the area. In the winter I go sledding or cross-country skiing, in the spring I hike, in the summer I swim in the river.
In world 2, I move to NYC. I get a small but adequate apartment in Brooklyn, really about the same size as the one I live in now. I am a subway stop away from my sister, and a short ride to work in Manhattan. My new job is sort of what I do already, just moreso. I make more money so I can afford the apartment. I work a couple of blocks from Union Square park, and a couple of blocks more to where my brother-in-law works, and we have lunch together once in a while. In my free time, I take advantage of the many many various weird activities I can do, though I often do them alone. I reconnect with some acquaintences and meet some friends of friends. It's more stressful, but exciting. In a year or two I find a job I'm actually excited about. I can visit the Valley whenever I want, though owning a car is a bit of a hassle.
So there it is. Either way I clearly feel I can do better than my current apartment. World 1 is safe and potentially boring, but pretty, and will allow me more time for making art. World 2 is more exciting but uglier, and has the potential to make me immobilized with anxiety. The dating pool in world 2 is vast; the one in world 1, not so much. World 1 is secure and homey; world 2 is a clean slate. This is my heavy decision. I have to make it by Thursday morning.
