If you always get stuck on one thing and can't let it go, you need to first analyze whether this thing is really important. If it is indeed important but you feel troubled because it is too difficult, it is actually a normal phenomenon. You should focus your attention on solving the problem. If you can't solve it for a while, you can listen to music, chat with friends, or go out for a walk or shopping to distract your attention. If the thing you are struggling with is insignificant but you just can't let it go, you can consult a psychologist.
1. If you always get stuck on one thing and can't let it go, you should first analyze what kind of thing it is. If these things are indeed very important to you, but there are certain difficulties and contradictions, and there is a dilemma situation, it is also a natural reaction to be entangled in this situation. At this time, your attention should still be focused on how to solve this problem.
2. If the thing you are struggling with is not important, or even something that has already passed, but you can't let it go in your heart. You also know that this kind of struggle is unnecessary or not worth it, but you still can't control it. If this is the case, a common situation is when symptoms like this appear during depression or anxiety attacks. It is recommended to consult a psychiatrist as soon as possible, receive professional evaluation and diagnosis, and accept professional treatment as early as possible.
