It’s a really bad habit, but I always compare myself to others in my school and feel like I’m never self-satisfied. Overall, I think I’m a well-rounded student but I’m not the smartest, most athletic, or involved in school. It stresses me out constantly, and I don’t know how to stop it.
Does anyone else feel this way?
I feel similarly, but for the opposite reason. I attend an inner-city and poorly funded public HS. Our top ranking students out of a class of ~ 700 both attended lowly ranked state schools last year.
I would be thankful for the fact that your peers challenge you to explore new opportunities. I sometimes find my uncompetitive school environment depressing and unmotivating. Point being: there are multiple angles from which competitiveness can be viewed from, so don’t obsess over your perceived imperfection in your environment, as there’s really no telling how you stand on a national or even global scale.
Run your own race. Take care of yourself and don’t worry about the other kids. This is your life, not theirs, and what they do and where they go doesn’t matter. Run your own race.
Thanks for the responses and advice! I have always been a very competitive person and it just feels nearly impossible to ignore other people or think optimistically, especially when they’re doing better than I am.
This is basically me in school 
I have a group of friends, probably top of the class and we keep comparing ourselves to each other, trying to get the better score (I loose most of the time lol). I think this is a good thing and my advice from this would be try to find some friends you can compare and compete with. Not an all out fight but a semi-friendly battle for better grades. It really helps you to achieve better things!
For the stress part, really many average high schoolers feel what you feel (same here) you have to just bull through it. High school and college is a small part of your life compared to your future. If you persevere now, imagine where you would be in 10 years!!!
This is a habit to break! But good for you for noticing now and thinking about it.
If you keep this up, you will find that you are dismissing people who are wonderful because you have rated them as less. And they will feel you are doing this too. Honestly, this will have a huge negative impact on your personal relationships.
Set your own goals. Don’t rely on external validation. It’s great to push yourself, not so great to do so simply to be better than those around you.
And there is almost always someone better somewhere. It’s a losing proposition.
Envy and guilt are two things that can lead to a unhappy life. Being competitive always involves knocking someone down. You might find more joy genuinely supporting one another. At the end of your life it won’t matter who got the highest grade or test score.
