hello. If your memories is bothering you, talk about it with your parents. it's not your fault. You might be sensitive to what is being said, or make something out that isn't there just cause you feel strongly about something. Emotions often do this trick to your mind, if you aren't talking about it with someone or has learned how to handle them. You are talking about this as "hysteria" while it's a conflict in your mind cause you haven't learned how to handle your emotions. Your anger is a result of this. You can manage this with reading up on emotions online or getting therapy. There is nothing wrong with how you feel, it's just something that you have misconcepted during time and the fault is that you didn't know what to do otherwise. You remember negative feelings cause of this, and you haven't worked through them properly, cause they're "bad" for you. While in fact they shouldn't be.
