After nearly 20 years, I feel things are at breaking point. My ageing, grief-stricken parents have to do everything for my brother, who has mental health problems and multiple addictions. I love him and am desperately sad for him, but increasingly can't tolerate his behaviour. My parents have to bow to his every whim, as he terrifies them with veiled suicide threats, blames them for his drinking at every turn, and essentially controls their lives (e.g. they can't go on holiday together as he makes it clear he will be very risky if they do). Every day revolves around what he might need (at unpredictable times). He always considers his perspective to be right. He rants at them, makes them endlessly apologise for doing things wrong (e.g. they brought him the wrong food last week, which made him very angry and "drove him to drink"). They won't stand up to him or tell him to do things himself as "he's so I'll" (true) and he might kill himself in upset or anger. What can I do??
TIA
