Awful family member

Hi.

I have a sibling who is downright awful. In the past two weeks, they have: said my disability isn’t as severe as theirs, undermined my chronic pain, swore at our mother, called family friends slurs, complained about a past holiday they did not financially contribute to at all, complained about every single one of my treating doctors, complained about me increasing my therapy because “I know you and I know you won’t be able to do it,” complained about getting less than ten hours of sleep every week day, complained about our mother not making them breakfast at the time they demanded, complained about mum being on the phone to other family members, complained about dad having a day off, set off my seizures by touching my arms when I told them not to, sent triggering pictures to me that I asked not to see which triggered my seizures, complained about me using the only disabled bathroom in the house when they wanted to sleep, screamed at mum in front of our cleaner and insulted her for misremembering information regarding my sibling’s medications, accused us of conspiring behind their back after they screamed across the house while venting to me about their work and my dad overheard and asked about it, and more I’m probably forgetting.

Today they have decided that it is my responsibility to ensure mum keeps her voice down while they are asleep. We were talking because I needed to go toilet and have medications, but as far as I remember everything was kept to a whisper. My sibling says they heard every word but what they reported hearing was never spoken between mum and I during our conversation.

Ironically, I have woken up most days this fortnight from their screaming — at mum, about work, yelling ‘help me’ because they dropped something (nothing broke and it wasn’t a massive drop), screaming because they couldn’t get a shoe on (they were indoors, not going anywhere).

My psychiatrist said their behaviour is provocative. He suggested they’re upset about external factors and taking it out on the rest of us. I don’t know if I care. I’ve posted before on the forums about my sibling’s behaviour and I’ve about had it with them and their entitlement.

I wish I could leave. I looked into out of home care facilities but my doctors discouraged me. I would ideally prefer to stay with my parents, but my sibling’s behaviour the past 16 months is driving me nuts. My sibling refuses to move out and my parents won’t kick them out because they threatened to go no-contact. I don’t care if they do. I just want a nice living environment, and I have that with my parents.
