I live in a different city from my parents. DB lives about a mile away from them.
TBH I'm not sure I can really do justice to this in a thread, because there's a long history of DB (who has addiction and mental health problems) controlling my parents. He does get better with age, I think, but it's been pretty horrific in the past. He also doesn't really like it when I come to stay, because it means my parents have less attention to pay to him (e.g., they quite often get a late night call that he'd like some luxury food item brought to him, and off they trot with it).
Anyway, I'm meant to be staying with my parents over Christmas. They have one nice big spare room, and one smaller spare room with a mattress on the floor. I'd just assumed I'd be in the big room. Got a call last night just to let me know I'd be in the small room, in case my brother wants to stay over Christmas night. He probably won't, I'm told, but they'd like him to have "his" room waiting, all made up for him, in case he'd like it.
TBH I'm actually fine with the mattress room, and the last thing I want is to cause aggro for my poor long-suffering parents, so of course I said "yes, no problem". But the more time goes by the more fucked off I feel. I love DB, and he does have a rough hand dealt to him in many ways. He suffers a lot. But FFS.
How can I make sure I let this go and don't get sulky over Xmas, given how cross I feel? AIBU to feel this way?
