I have been feeling very bad and guilty lately ,I had rejected a guy 2 years back and had also blocked him once ,whenever my teacher used to tell him to sit with me I used to make an annoying face ,I had liked another guy who doesnt like me back ,I ignored the guy who liked me a lot ,he used to try to make an eye contact with me all the time ,but I used to ignore him ,but when vacations started due to covid I realised my mistake but school was closed for 2 years,and now I am passing out from school ,I am not able to study properly because I keep reliving the past moments when I had ignored ,I am not able to help myself ,I cant forgive myself that I had hurt him ,please help me please
