My sister moved abroad with her husband twelve years ago. She was the bubbliest, liveliest and most chatty person that I knew of. She had two children since then, but after her second son (he's 3 now), she seems to be a completely different person. She went quiet, not quite engaged on our family's What'app group, posting nothing at all on her facebook, always in rush to end the call which is understandable with a toddler around, but she also does it when he's asleep.
My mum visited her last year and she also noticed that my sister prefers to be alone most of the time. It's not helping that her husband works very long hours and she has to do all the children raising and house duties on her own.
We spoke this morning and I informed her about an acquaintance who passed away and she said that she feels secretly jealous whenever she hears someone's dead. She said that this life is full of shit and responsibilities with no end that it's not worth living. I tried to change the subject and sent her a cute picture of our cousin's newborn and her only comment was " I feel sorry for X (our cousin), her life is ruined but nobody will tell her that".
I told her that she sounds very exhausted and I promised that as soon as we can travel again, I will be keeping her children so she can go on a long holiday with her husband. She laughed and said "Never mind, I'm fucked forever!".
She did tell me that she had PND after giving birth and was seeing a professional about it, but she won't open up anymore. I'm so worried about her and feel completely helpless as to what can I do? Any ideas please
