We have a family group chat with just my siblings and parents. One of my siblings posts daily about all their minor major and in-between frustrations. They live a happy life but when it comes to texting they are generally quite a negative person.
I just wake up everyone morning to their negativity, get updates on their frustrations each day. I just feel they unfairly dump all their emotional load on us. I wouldn't dare raise it with anyone else and my attempt in the past to approach sibling and ask them to scale back was met with them telling me to leave the group if I'm not happy.
I am particularly upset today because I have heard some really rubbish news. I called and told my mum over the weekend who was with my sibling, so they know about it. I didn't put it into the group chat. Sibling is now complaining again about their day again and how their bus was late etc and I just want to tell her to STFU.
I don't want to leave the group because its wonderful getting selfies from my dad when he bumps into one of my friends, and interesting facts and news from my mum.
Is there a way I can get sibling to stop indirectly. Also sibling is married with a supportive partner so it's not like they don't have anyone else to message.
