In fact, as the so-called experts say, it is basically useless to listen to music or do something else when you are in a bad state.
I think the best thing is to keep studying even if you are in a bad state, which can slightly reduce the learning intensity. Although you look tired and like to force yourself, you will gradually find that you can master yourself at any time. In fact, I have been telling myself that although I am in a bad state now, studying is more rewarding than not studying. You may not feel it now, but I think what I forced myself to learn when I was distracted finally worked, and when you are under increasing pressure, everyone is under great pressure. When others can't face the pressure and don't study, although you are under pressure, you will be better than studying.
Actually, that's what happened. You're not in good shape. Maybe many people are in a bad state at the same time, but you can't see it, so you think it's just you. In fact, everyone is like this. Now that you have learned to respond positively, you will be better than them.
Therefore, I suggest that you don't seek other ways, which will cure the symptoms rather than the root cause. Sometimes, literati and scholars will find that you have found your own pleasure again, which is often the case, so don't blame yourself, don't give up on yourself, stick to it, and at every moment, you will surely defeat yourself and others.
Interest is the most important thing. You want to do the next question, if you get it right. If you keep making mistakes, you definitely don't want to continue studying. I suggest you don't look at anything else. Do what the teacher said several times first, and think carefully about why you didn't understand it at that time, what's the difference, which one you didn't understand, or how to string together the knowledge points. You must really understand through repeated reading, and your grades will improve.
Stay away from things that interfere with you, such as the internet, hurting friends and so on. Regain motivation. Learning needs passion, but passion does not appear for no reason. When a motivation can no longer support itself, find another one.
Know how to control your emotions and be in a "constant temperature state", not too impetuous and not too extreme.
