Do you ever think of that moment in life that “changed you”

Lately it’s just been weighing heavy on me. I don’t really want to type it all out at the moment partially because I’m afraid people will think it’s stupid anyways. But anyways I remember the exact moment that changed me in life. I was 17 at the time and I swear before that day I was the most loving, caring, sweetest kid/person on earth. But this one day literally changed me into something unrecognizable and ever since that day I stew with hate. Even in good times the hate still simmers just below the surface. I’m 32 now and I know for a fact this is the moment that changed me for the worse and I don’t know how to change or go back 😞😞😞
