How should we treat the performers in the dormitory?

At first, it was fine. A lovely girl likes to giggle every time to make others happy. Later, she felt more and more embarrassed. Emotionally, every time Y tells us about her boyfriend, she tells us how much she likes and loves him. Her boyfriend often sends her something to show his love every day, and she feels very happy every day. She has a little skin disease and has always felt inferior, so we just want to praise her and make her more confident. It turns out that boasting too much will make her overconfident.
