Dazed and confused

I will warn you, this post is not going to make any sense at all because I will not use names of real people. I won't use any names at all so you can avoid it now if you want.

I have a job. For that job I am being asked to do things I do not understand. It's not that I don't understand why they want me to do something. It's that I do not understand what they are telling me to do. They are talking language that they think I understand and I don't. As a result I honestly have no idea what they are talking about and so have no idea how to even begin to consider what they want me to do. Since I don't know what they are talking about and don't have a clue as to how to do it, I'm just going to continue on doing what I've always done. If it's wrong, I'm sorry. If I lose my job over it - Oh well, sh*t happens. I could probably ask for clarification, but quite honestly I don't think I would get an answer that I would understand so why bother. In my case, I would need them to point at things and say this is right and this is wrong. I don't see that happening so what can I do??? Just remain calm and carry on.
