My sister is in total control of my mom in every way (by their mutual agreement). Last time I visited there from out of town I called my mom on her landline and got a message that the service had been temporarily disconnected. My sister had apparently forgotten to pay the bill. Then my mom gets a credit card statement in the mail that is much higher than usual. She has my sister pay the whole balance every month. Well, my sister had only paid $100 on a $500 statement the prior month, so there was interest accrued. Anyway, my mom asked my sister about it and she gave her some lame excuse why the total amount wasn't paid. Mom also told me the doctor had specifically told my sister that she was to dispense my mom's pills for each dose. She wasn't doing it, so my mom was doing it herself, and I witnessed her confusion over trying to sort them out. My sister had gone out of town for the week without concern for my mom's meds.
I think my sister and her new deadbeat boyfriend are spending a lot of time getting stoned on pot. She admitted to my brother that that is what new boyfriend does most of the time. So I can only assume she's doing it too. My concern is that my mom, totally dependent on her to take care of any and all of her needs (by choice) is being taken care of by someone in a marijuana fog most of the time.
Should I get involved and do something about this or just ignore it? My mom seems happy enough and is oblivious to my sister's altered state. The problem is my mom will defend her no matter how neglectful she gets, so I worry that this is just going to get worse over time. Anyone dealing with this kind of situation?
