When I cry and my mother catches me, I tell her what's the problem. But after she left I regret talking about it. Why is that?

Well... when I was depressed I didn't want people knowing about it. Perhaps you're worried she'll catch on?

well i am sorry to hear about your brother! but if 你 regret talking to your mum try talking to your brother if 你 trust him of your 老友记 because they are sure to care if they are good 老友记 hoped i helped
