Not sure this message will find you, hope it does. You're 20 and made a mistake, that's ok. Really it is. At 20 years old there is usually very little chance of being an out the gate success, its rare. But what this experience shows is you have guts and clearly a ton of ambition. Believe me, this is a tough time but do your best to recover, its time for plan B. Go back to school if you want and look for other jobs. Once you get back on track you will truly value this experience because when you are ready to try again, you'll come more prepared. Good luck and keep your head up.
