To be honest, something is a miss. I have a few friends that traveled to the US with practically no money and were able to rent their own place, buy a car, dress well and they don't have any particular skills.

Drop tech/coding for the time being. Go take a minimum wage job, any job, that you can find. There are low-barriers jobs out there like washing cars for some random guy. This should provide you enough for food/gym and within less than a month you should be able to rent a room.
