i think you need to step away

That's exactly what my professor told me this morning before I left class. I had spent about two hours trying to figure out one little thing on the computer, asked him multiple questions, then started tearing up. He sat down next to me and patiently explained - again - what was going on. Then he said to me, "I think the problem here is you are way too stressed. You need to remove yourself for a little while. Before you do the other section, I think you need to step away." So I said ok, saved my work, and shut down my computer. And that was it for class for the day...sometimes the best thing to do is just step away.
