"Everybody is a genius. But if you judge a fish by its ability to climb a tree, it will live its whole life believing that it is stupid." - Albert Einstein

While I disagree that everyone is a genius, I think that everyone is good at something. Perhaps this isn't your strongest area, but keep in mind that you are still quite new at it. Your co-workers have studied this in college, they have had a lot more practice than you. 2 months is not nearly long enough to master something.

Not sure how long probation period is for you, but here it's 3 months. If you have not been let go by the time your probation period is over, that is a very good sign and it means they want to keep you. Keep trying your best, that's all you can ask of yourself.

If it turns out that this career field isn't for you, and you decide to move on to something else, don't consider it a failure by any means. I tried several jobs in the food industry before accepting that it was too stressful for me, and I couldn't handle it. Am I a failure for that? Absolutely not. Everyone has their strengths and weaknesses.
