I have no idea if what I'm experiencing is anxiety, but I'm not really sure what it is.

If I ever make the slightest error in anything I do and it gets noticed by someone else, I can't stop obsessing over it. What I should have done instead, what they think of me having made that mistake, why did I even do it in the first place?

If someone asks me to do something I haven't done before, I need them to explain step by step exactly how it needs to be done, or better yet shown. Otherwise, I'll be worried the entire time that I'm doing it wrong.

Even typing this post now, I'm concerned I'm asking this in the wrong place, and that what I'm describing isn't anxiety and I'm wasting everyone's time.
