I have a weird problem. In one of my classes, I have a relatively good grade. However, for some reason, I feel as if I don't deserve this grade. I have this strange feeling that I "cheated" in the class and should have a lower grade. Throughout year, whenever anything that may be considered cheating happened, I spoke to the teacher and each time she said that it wasn't cheating. My main issue is that I will be applying to colleges in the fall and I am scared of getting into a college that I don't deserve to get into because of this "cheating." I am not sure if anyone else has had this problem, but advice would be very much appreciated. Thank you!
I don't know your particular situation and can't look into your soul. Perhaps you feel that you don't deserve anything valuable also outside of the education setting. Then this might be a topic for discussion with a counselor, therapist or just for an honest talk with a friend.
But more likely, in particular if these thoughts are limited to university/college etc., you might suffer from what's called 'impostor syndrome': A more or less constant but unfounded thought that your success (in education) is just a matter of luck and has nothing to do with your intelligence or hard work or both. In other words, you have become used to attributing success to your environment and failure to yourself. Since most people around you hide their failures and emphasize their successes, your observations tend to confirm what you already believe.
This leads to fear of being 'found out' eventually, in which case you might imagine that your entire career will collapse like a house of cards. Irrational fear of having (involuntarily) cheated fits the bill. After all, if you are affected by impostor syndrome, you think you're cheating all the time.
But of course, if you are the kind of person who asks their teacher to consider whether you might have cheated, you most certainly will never do so. Think about it for a minute (and perhaps have a good laugh). The link above and other answers on this site can help you cope with impostor syndrome. But perhaps the most important thing is to know that it's a delusion.
