The original poster didn't do well on the college entrance exam because of poor decision-making. He doesn't want to make the same mistakes and fall into anxiety.
Anxiety is a powerful emotion that has been with us since we became humans. It reminds us of dangers ahead. We are uncertain about the unknown, and as humans, we become anxious about the uncertain. When we feel that we are in danger, anxiety will alert us.
He's a cute friend. Don't reject him.
Why did he jump out to remind us?
The essence of your question is:
How can you do a thing well without letting emotions get in the way?
My answer is to just get started. We don't know what will happen tomorrow, so we just need to get started. Time will tell.
When we do something, we plan what to do first, what to expect in the middle, and then solve any problems that come up. We shouldn't be so overwhelmed by anxiety that we can't think about our problems. Not being able to think means wasting time and energy.
The environment is important, but you are more important. We can look at the environment from a different perspective. If people around us don't work hard, I work hard. I stay pure in the midst of filth. I work hard, and I have an advantage over them.

I can totally relate to feeling lost during high school. It's tough when you're surrounded by distractions and not the right people. Realizing that your environment was affecting you so much must have been a big moment. The regret you feel now shows how much you've grown since then. Everyone makes mistakes, but what matters is learning from them.
Sometimes we don't realize the impact of our choices until much later. I went through something similar and it took me a while to understand that my actions had consequences too. It's hard when you see others succeed while you feel like you're falling behind. But remember, there are always second chances if you're willing to put in the effort to change.
It sounds like you faced a lot of challenges back then. It's easy to fall into the wrong crowd or lose focus on what really matters. I admire that you're reflecting on those times now and trying to figure out better ways to handle anxiety. Life gives us these lessons for a reason, and it's great that you're determined not to repeat past errors.
Looking back, it's clear that high school was a rough time for you. Being in an unsupportive environment can really take its toll. It's unfortunate that you couldn't find the motivation earlier, but it's never too late to start anew. You're thinking about your actions and their outcomes now, which is a huge step forward. Keep that mindset, and you'll likely make better decisions going forward.
Reflecting on past regrets can be painful, especially when you see others doing well. High school was just one chapter, though. What's important is that you've recognized where you went wrong and are committed to growing from it. Learning to balance anxiety with action is part of maturing. Just keep moving forward, and don't let past mistakes define you.
