When I was tempted to talkback, I wrote this

Better ignore those you don’t really need;
I mean stories that doesn’t make your life any better.
Her chatters won’t stop, I thought anger can stop it, but sadly made it worse, doesn’t make it any better.
You have to choose yourself, choose to listen to your quiet self, she deserves to be listened to.
Even if the one that’s so close to you kept on talking and she will become crazy in the eyes of many if you don’t really play along with their drama.

This time you have chosen yourself; if they needed somebody to listen to them, they have to talk to a psychiatrist or a psychologist.
Just let yourself ignore those voices that you don’t like listening.
Sing your own song, be the best you can be.
Show them that you are able to ignore them, come what may.
You’ve already cared enough, it’s your time to care about yourself now.
