Im 16 and I have a 14 year old sister, we fight constantly. I don't mean to but I get so angry with her I feel out of control. I don't know how to get along with her, everyone says to deal with it. They say its just sibiling rivarly but I thin she really hates me sometimes.
Please, I need help. I need to stop getting so angry with her, our mom passed away in April and my dad is not great with teenage girls. I don't want her to hate me.
