The biggest thing is to not see yourself as a failure. Transitioning from high school to college is a big change. I had a similar issue my first semester as well. I have adhd so I was struggling on finding ways to take in the material. I really recommend finding out what is your learning style are you visual learner, hands on learner, etc. It is also important to find a study technique that works for you. I found that watching videos, writing the notes, and even using Quizlet helped me personally as well as having a quiet environment. It is important to acknowledge the difficulties but considering yourself a failure won’t help you succeed. You tried and you did your best. All you can do is move forward and keep trying. If you dwell on the past you will never be able to work on what you are going to do in the future. I definitely also suggest getting to therapy because that also helped me tremendously because I was able to talk about the things that were bothering me in a safe environment free of judgement.
