What is your worst memory?

My worst memory is my mother telling me I'm a disappointment. I remember when I was 13, I was going through some things, so of course I wasn't happy. One day, on the way to the store, she said "Just because you're miserable, doesn't mean you have to make everyone else miserable. You're being selfish. This isn't how I raised you. I am truly disappointed." I try to forget it, but it won't go away. Every time I think of it, I remember exactly when, where, and how she said it. I cry just thinking about it. Ever since, my self-esteem lowered, and lowered, and lowered, to the point I wanted to die. Remember to defend yourself. Thank you for reading.
