Why not ask Chris? Explain to him your frustration and ask him if there's something you need to be doing that you're not? From how you've spoken about him, he seems to be a good guy and I'm pretty sure he has confidence in you or he wouldn't have hired you. You can make yourself crazy with what ifs (I know, I do it to myself all the time), and I know how scary it is because you ask yourself if you really want to know the answer. Paranoia is one hard-assed bitch.

But I think you're fine! You DO have talent and I think you've done far more in your time there than most apprentices do in the same length of time.

And don't chew TOO hard on those fingers, you need them to work! And type!
