Welcome to Heathcare Magic and thanks for your question...
From your brief description, I understand that you have been suddenly having diffifulty in concentration and feeling disinterested in your normally enjoyable activities. Since you have mentioned that it has been sudden, it is important to know if there have been any recent changes in your personal circumstances or social environment or if you are in the midst of a stressful situation. Excessive stress and difficulty in coping is a common reason to feel disinterested and detached from studies and other pleasurable things. There is also a possibility that you may be going through a depression
, in case you have other symptoms like negative thoughts, feeling low, reduced energy, poor sleep / appetite, etc.
My advice to you would be to talk to and share your feelings with someone close to you, especially if there is something bothering you. In such situations, it is also important to try not to isolate yourself or spend a lot of time in solitude, as it can worsen your symptoms. If you find that your symptoms are severe or worsening or affecting your day-to-day functioning, then you need to seek professional help, probably from a psychiatrist
All the best.
