My friend kept interrupting me so I ended up yelling at her.
Why do you think she was interrupting you?
She kept wanting to saying something but I was talking.
Being upset with her for not letting you speak is perfectly fine but you shouldn't have yelled at her for it. Let her know what she's doing and if she's your friend she'll make an effort to stop.
She won't listen to what I have to say.
Give a few days. She probably needs more time to get over it.
