Dear lllias:
You asked, “Can someone please tell me why I continuously get mad at my girlfriend and why I flashed out in an angry way?”
I detected one thing that is a reason for a person to get angry “everyone kept saying these hateful remarks like how poor my family is”- I assume you felt angry when they said what they said, didn’t you?
And then maybe you didn’t tell those “friends” that you were angry, didn’t express your anger at them but instead expressed it by slapping your girlfriend’s arm. Is that what happened?
