my teacher said something very mean to me and I still couldn't forget about it after 10 years. Why is that and how should I deal with my feelings?

Dear friend, I am sorry to hear that your teacher said something hurtful to you and that it still bothers you after all these years. It is understandable that such an experience can be difficult to forget or let go of, especially when it involves someone in a position of authority or influence. From a Buddhist perspective, our thoughts and emotions are interconnected, and negative experiences can create deep imprints on our minds that can be challenging to release. From a psychological perspective, such experiences can affect our self-esteem, confidence, and sense of worth, leading to a range of negative emotions such as anger, sadness, or anxiety. It is essential to acknowledge that your feelings are valid and understandable. You have the right to feel hurt and disappointed by your teacher's actions, and it is natural to want to seek closure or resolution. However, holding onto these feelings for an extended period can lead to suffering and prevent you from moving forward in your life. Therefore, it may be helpful to use mindfulness techniques to observe your thoughts and feelings without judgment or attachment. This way, you can develop a sense of self-awareness and self-compassion that can help you process your emotions in a healthy and constructive way. From a coaching perspective, I would suggest reflecting on how this experience has affected you and whether it has impacted your relationships or goals in life. You may want to consider seeking closure by talking to your teacher and expressing how their words made you feel. Alternatively, you could try writing a letter to your teacher, even if you don't send it, as a way to release your emotions and gain clarity on your feelings. Finally, you could seek support from a therapist or counselor who can help you process these emotions and develop coping strategies that work for you. In summary, it is understandable to feel upset and hurt by your teacher's comments, and it is crucial to acknowledge your feelings without judgment or attachment. Using mindfulness techniques, seeking closure, and seeking support from a therapist or counselor can help you process your emotions constructively and move forward in your life.
