Family Issues Support Group
Family issues is a huge range that go from minor conflict to major misbehaviour and even abuse on the part of individual members of the family occur. Whether you feel you are in a dysfunctional family or you're dealing with a very specific issue, this is the place to talk about it and find others who might be going through the same thing.
I tried to junk the wreck but couldn't find a junk yard that would take it! My sibling who goes through cars like cheap cigars said he wanted it. I explained to him everything that was wrong with it and how it was really just a big pile of spare parts no one wanted. His response was "You just don't understand cars."
So I let him have the car. His wife drove it 20 miles into town for groceries shortly after they got it. When she came out with the groceries the battery and alternator had died stranding her.
So not my fault.
And it's not your problem that your sister isn't listening to you. Let her live there. You obviously can't stop her, she won't listen. Those are her issues. She apparently is someone who needs to learn the hard way. That's sad, but it's not your fault.
I also have siblings with somewhat skewed views of my life and our family. For years I thought I'd been making progress and they were finally coming to know me and like me. In the space of a few months last year I realized that really wasn't the case, and that we were just never going to be friends or even really respect each other. Apparently I'm not deserving of respect for reasons that elude me.
They're entitlted to their opinions, but they are only opinions. They don't know me well enough to get to pass judgement on who I am. I suspect your sister is much the same. She sounds like she has issues she's trying to pass off onto you so she can go on about her life. Don't let her make you responsible for her issues. If she gets sick, you are not responsible.
