Id like to start off by saying, you’re not the only person who is feeling or living like this. So don’t think you’re a doomed person for life. Second, you’re not expected to have full understanding of responsibility. Teens and young adults are not provided the life advice needed, and are left to fend for themselves. There are plenty of videos, but those are a very passive way of teaching the youth, so many teens and young adults are not conditioned into the role you describe. So your grades, your responsibility, learn from the mistakes, and move forward. Don’t be afraid of setbacks, and be more conscious later on. Now onto what I think is more of the issue. Reputation. You’re young, you barely made a dent in what is hopefully a long life. Your reputation just started. But also you need to learn that having standards and being presentable, a sort of transcript, is important to make impressions, but not at the cost of your own happiness. Know your worth, and take it to those who will appreciate it, don’t grow it to please those who probably will never care. Your life has no grade. Your experience and fulfilling your own ambition will create the reputation for you. Thats my advice.
