How do I get my sister to stop being mad at me

do something nice for her like make a portrait of her

Explanation:

so she can stop being mean to you

I completely understand you 100%. Sometimes my sister will yell at me and call me selfish when I didn’t even do anything or when I’m not able to do something for her. When people get mad at us for no reason and say hurtful things it’s mainly about them and not about you. It could be she’s insecure and when she says she’s mad at you she’s really mad at herself. People who are confident in themselves and have a good heart do not hurt others. Remember that. Also it gets better usually with age. Time will pass, you will each move out and build your own lives and mature. Just ignore her for now and stick up for yourself when necessary. Don’t say hurtful things back or do anything vicious. Just stay calm and remind yourself that no one has the right to hurt you it’s their problem not yours. Good luck
