I am absolutely at my wits end, and starting to get quite depressed. I'm a single mum of 14 and 11 year old daughters. The younger one has ADHD and a good relationship with her dad and stepsiblings. She is not great socially, and has anger outbursts, but most of the time is caring and very kind. The older one does not have a great relationship with her dad (or almost anyone e else at the moment) is horribly negative a lot of the time, but on her own is an absolute joy to spend time with. They hate eachother. They can't compromise, can't tolerate eachothers presence, constantly shout at eachother - especially over the xbox and TV and are so spiteful it make me cry. For context, we have 3 tvs, one just for the xbox with a small screen, 1 family to that has the BT package and can also be used for the xbox, and one in my bedroom with a firestick. The arguing about the xbox is really getting to me, and I honestly hate it. Any tips for creating a happier home? Sorry for the long post but I desperately need some help.
