So, it's a long story, but here's the bones of it.
My brother is 4 years older than me and I believe he has mental health issues but we can't talk about it unless he's actually having a breakdown.
He's never held down a job for more than a few months and only scraped a 'pass' degree as a mature student. For years he wanted to 'make it' as a musician, but although he was briefly in a cover band touring the NW of America in the 80s that hasn't really come to anything.
He lived in a foul bedsit in KingsX for many years, and when the building was finally demolished he moved quite close to me, but we only really saw each other at family events at my house or my Mum's (he became estranged from my father about a decade ago). When that became untenable he moved to my Mum's place in a market town in Wiltshire.
When he has a breakdown or becomes manic my Mum relies on me, but when he's stable, she won't even acknowledge there's an issue and if I try to raise it with him, I'm pathologising him.
This is becoming more of an issue because my little family (hubby and DD) are moving to the States in a few months and my Mum is desperate for us to 'build bridges' despite the fact that I feel like he's burned all the ones I've build, despises my husband, and has no interest in my daughter (11 going on teenage).
I'm not sure how to deal with this when I'm closed out of any conversation about what's going on with him.
