Massively Fucked Over 12 hrs before moving cross country

Okay guys. Me and my friend planned months ago for me and her to take a cross-country trip to California so that I can move from New York to California, and so she could do a trip after her college graduation. It worked perfectly. I confirmed with her that she could still do this multiple times before now (bc I’ve always done everything alone and independently, so when she offered, I really really really wanted to make sure that she was actually serious). I have been on my own since I was 16 and have learned to not depend on anyone else but myself. But this ONE. TIME. I. DID. Flash forward to 12 hours before my trip and she backs out. Ghosts me after. I already have an apartment that I paid rent for in California. I’ve had this plan for months. I genuinely have no idea what I’m supposed to do. I’ve been so massively fucked over by this girl with no explanation 😭 (I have my dog, my lil snake, and 3 guitars w me one of which is my late dad’s.) I have done cross country trips alone before so I could drive but I don’t have a car 😭😭😭
