Ah, sadly that's fairly standard - hire a cheap junior developer, expect the world of them, and fire them if they show even the first sign of not being able to do everything they ask with 100% certainty. It may not seem like it, but it's a good thing to experience a shitty company, because you'll learn as much from how to not do things as you will from the "right" way. A lot of people have touched on the focusing part. To be honest, I think that you sound like an absolutely normal developer, and all you need is an opportunity to grow at a good company. Out of interest, have you considered working at an agency? In my experience, they're a nice place to start out, because you get to work on numerous small to medium sied code bases over the space of a year, and the breadth of work allows you to build your experience while keeping time pressure on.
