You're not a bad person and sorry but i assume you're a teen? When we are experiencing our teen years, it's probably one of the toughest and weirdest time of life. We are maturing, hormones rage at times, we are learning all about how to be properly social and sometimes we just fail at that. Also teens are ego-based individuals (i was and so were all my friends in their teen years, so i'm not picking at you). During the teen years, we have difficulty learning about self-control and that we aren't the only people on earth with feelings.
You are a good person. If you want to learn a bit more about life, do some research on gratitude, self contentment and also about caring for others.
But honestly, i think you're going to be fabulous! Why? Because you're concerned right now and you want to do the right thing.
