I have a younger brother and a younger sister.

I don't really speak to my brother. I see him a couple of times a year when the family gets together but we don't have anything to talk about anymore. He's autistic so maybe he can't help it but he's impossible to have a normal relationship with. He's never had a job because he cant be trusted with any kind of responsibility. He can't stay away from alcohol if it's available and he can't handle it at all. It's always the same when he drinks. First he gets overly excited and it's very awkward because his whole personality changes. Then he gets easily irritated and gets into arguments about petty stuff nobody cares about, but he just can't let go.

He regularly texts family members about how they have let him down when he's getting drunk at night. He gets way more support than he deserves though. Once he just texted me "I'm sorry" and turned his phone off. Naturally I got worried when I couldn't reach him so I called mom, she told me not to worry though, turns out he just does that sometimes.

My sister and I get along much better but I worry she's losing it. She's easily the smartest and most socially capable of the three of us but she's never had a job outside of telemarketing and now she's too depressed to work at all. We don't have many relatives but the few we do have have a tendency to end up alone, bitter and severely unhealthy as they get old, and it's starting to seem like that's where she's heading.

I'm very worried they're both gonna come ask me for money when our parents are gone.
