What you are experiencing is very common after a stressful or traumatic experience. Even when the situation is solved in real life, the brain does not always feel safe immediately. Your mind is trying to protect you by replaying a few specific memories again and again. This is called a trauma-related thought loop.
When you try to force the thoughts to stop and they become stronger, that is not your failure, it is how the brain reacts to threat. It means your nervous system is still holding fear, not that you are weak or overthinking.
Next Steps
The most helpful next step is to speak with a counsellor or psychologist who works with trauma. Techniques such as trauma-focused therapy, grounding work and cognitive processing can help your brain slowly release these stuck memories.
Because this is already affecting your studies and confidence, early support will make a big difference and help you return to normal focus and self-belief.
Health Tips
Do not fight the thoughts. Instead, gently tell yourself: “This is a memory, not my present.”
When a thought comes, shift your body into the present using a simple grounding exercise (look around and name 5 things you can see, 4 you can touch, 3 you can hear).
Keep one small daily routine (short walk, shower, tea break, prayer, music) to help your nervous system feel safe again.
Limit self-blame. Trauma reactions are automatic,they are not choices.
Be patient with yourself. Healing does not mean forgetting the past; it means your mind learning that you are safe now.
