I felt exactly the same way when I was 19.
Eventually I was forced to get a crappy job just so I could eat. I saved up all my money for 4 months, then quit working until the money run out. I was able to make that money last for over a year by being frugal and in the meantime I developed a strong sense of purpose.
So consider early retirement, where you don't worry about the future and just do whatever you find enjoyable
