Look at it a different way. At a very young age, you moved across the country, that shows guts. You found a job right away, that shows initiative. You are concerned about your account being overdrawn, that shows responsibility.
Yes, that job turned into one royal mess, but a year from now, you and your friends and family will laugh about the job from hell.
You made a big move, and have decided that it is not the place for you...and there is no shame in that. Moving back does not mean you will be living in your childhood room forever. It just means that you want to be in a safe place for a little bit before setting out on your own again, and that's okay. lol, I remember that restless feeling very well, you won't be staying with your mom for very long.
