Identification card? Birth certificate? Passport? Expensive, but not at all difficult. Building credit was the hardest part, it also took the longest, but it wasn’t impossible. I just pretended that the life I was living was the one I was happy with for another year, bought things on a hard-obtained card, and paid it off quickly. The most underhanded part of my plan was lying to the bank in order to open an account. Luckily, I was able to deal with an overly sympathetic older lady who believed my story about an abusive spouse. I didn’t really want to lie, not about that, but my research provided no other answers.
At the end of the year, with an alright savings balance, and okay credit, I left. No warning. I packed only my most favorite things into my modest car, and disappeared. It was, by far, the easiest portion to enact. No looking back, no regret.
