Dude, you ultimately did the right thing. You had to know - so you found out. And now you know, you're exactly where you need to be. On a FRESH canvas. What most people would see as a disaster, you can now see as an opportunity. You can be anything in the world that you want.
You obviously have the skills of someone at management level - THAT can't ever be taken away from you. So you're not hopeless. If you were a rich kid who hadn't worked a day in your life, and didn't have the skills required to support yourself, then I'd be worried. But you've been at that level once and you did it by yourself. So I know you're going to be golden.
What you did is the very secret to success. It's all trial, error, failure, lessons learned, more trial more error, disappointment and defeat.
Eventually something will work, and it's because you've earned it by messing up enough times to know what not to do.
Wow, that went off on a tangent...
Anyway don't worry. Everything is as it should be.
