My sister had a baby girl 3 months ago. She has always been a bit depressed but after the baby was born her situation has worsened. She keeps accusing her husband and our mum that they dont care for the baby and have ruined her life and the baby’s life. She keeps saying that if it gets too much she will kill the baby and herself. She doesn’t listen when we try to reason with her and is not eating drinking properly. I have know idea what to do. I’m worried that if we pressurise her too much she will do something bad. But if we are ignoring then the situation is only worsening day by day. I love her but sometimes in anger she says such hurtful stuff that at the moment even i lose my self control. And she is always blaming our mum for all the bad stuff happening to her which is not true because our mum has sacrificed a lot to get us to where we are. She has already had a troublsome hard life.. i’m not sure how much more she can deal with now. Scared and lost!! Plz help!
