If you lost half of your income, but got memories of a a version of yourself living a life of leisure with that part of your income every night, would life be better or worse than it is right now?

Oh god no. Not for any amount of money. What a total mindfuck that would be. Any person you meet, you wouldn't be able to tell if you met them before or if your memory twin did.

You would constantly be questioning everything you see and hear.

Small things would drive you crazy. You distinctly remember going to the grocery store yesterday, so why is the fridge empty again. You swear you washed your clothes yesterday, yet everything is dirty. You remember hearing the doorbell, but no one is there.

Bigger things would make everyone else think you are crazy.

Your best friend who you hang out with every weekend? Nope, your memory twins best friend. Just a casual acquaintance in this reality. And they get more weirded out every time you tell them you had a great time last friday.

You are talking to your wife of 20 years only to realize its not your wife, its your memory twins wife, this version of her doesn't know who you are, and she is panicingly trying to find her mace. The children you love, care for, and have watched grow up doesn't exist in this reality.

Then there is the repeated heartbreak when those people that are the same in both realities diverge in terrifying ways. You remember visiting your mother yesterday, talking to her, telling her you love her, hugging her goodbye. You also remember her dying 10 years ago and know you'll never see her again, except for in memories that keep coming that are not real.

Eventually you would just give up, accepting that you can't keep remebering two lives at once. So you withdraw from society. Lock yourself in a room and slowly wither away as you remember a better life happening right now.
