Congratulations - this is what it's like to go from the lowest level of knowledge (Knows nothing and knows not that he knows nothing.) to the second lowest level. (Knows nothing, but at least knows that he knows nothing.)

The practical solution to this problem is that, in any decent organisation there are people much more competent than these two levels, and it's been obvious to them that you know nothing for much longer than it's been obvious to you. Their expectations will be set accordingly, and they will probably help you out - if you're willing to take some advice.
