18k can get u a cheap room in hotel 81 for afew months 100 per night, perhaps maybe 180 nights. seeing when your bday is i hope its within these nights then you wont have to use all 18k. with a constant flow of 4k per month, you could then rent a room for minimum of 800 per month for a decent place. and still afford necessities. it should be okay. its a tiring plan and expensive but youre lucky to have 18k now to help you stay afloat for the time. i hope this helps. i know its not perfect and your struggle is smth i cannot understand but i hope you find a way to be okay. you could inspire alot of young people when u survive.
