Judging from your previous HN post i take it that your reason for quitting was because you hated where you were working and were being worked out. Its difficult in such situations, but you have to be prepared to lower your expectations cause they may be set too high and that is why you are feeling bad. A lower paying job can be really satisfying, you are young and can build your skill set. Even if you were much older you can still build your skill set. Start from somewhere you can set you feet in and go from there. I would like to read a post of you succeeding in your next endeavor.
