Just remind yourself that it wasn’t of your doing. If it were up to you it would be different. All you can do is cherish the individual relationships you have and hope they will reconcile before it is too late.
My family was really disfunctional. Multiple MH staff said as much and that that it was not good for my recovery to live with them. But unfortunately I couldn’t find anywhere permenant to live for a long time so I had to put up with it for a long time.
I see my mum still but I don’t have any contact with my Dad or my siblings and don’t really miss them. Christmas is the only time of year where I feel like an outcast. The rest of the year I’m glad I don’t have to deal with their nonsense and hostility.
