The good news is, you're 20. You have plenty of time to recover from this experience. You can even go back to college at this point, graduate, and still only be 24.
The bad news is, 4 months of living expenses is not enough to eject from stable income if you dont have replacement income waiting in the wings. This is something that seems to be overlooked in the folklore of "living on ramen". The fact of the matter is that you need money to live, and if you are worried about where you will live or where your next meal will come from, you will not be in a position to be able to concentrate on any major intellectual endeavors.
