So recently my mom Has been really really stressed out, it has been a rough year we lost three family members and my mom has been out of herself lately.she has managed to tell me that she is suffering from depression and any little thing can get her mad or sad or crying or really happy (she's not bipolar she's just really sensitive lately ) and I told her to go talk to a doctor a friend or me. And her answer was I will not talk to anyone and I really want to help her but she won't talk to anyone and I don't want her to get too depressed or depressed to the point that something bad happens please help
