Its polite to respond to ppl instead of just flat out ignoring them when they speak to you. But if you don't feel like talking and feel more quiet, that's ok to say that to them too. Is it possible for you to leave the room when you are feeling like they are being too loud for you?

I'm sorry someone mistook your cup for theirs. I'm sorry they hurt your feelings and it made you feel suicidal do you have anyone working at your home who you can reach out to about things like that?
