I (26F) am asking this for a friend (23F). We have known each other since 2018 but lost connection for a year or two due to her needing some time to deal with her strict and judgmental family. We recently reconnected and started hanging out more often around May of this year (she texted me happy birthday out of nowhere so that's how I can remember lol).

After months of catching up, I found out that her and her sister (24F) moved out and are currently living together. She also has a boyfriend (23M) which I am super happy about since he is pretty much her support person and she feels very comfortable with him. She recently shared that she wanted to do more with her career since she doesn’t like working with her current coworkers (she works in a kitchen at jail work center facility) as they are rude and mean. I suggested her to pursue something in medicine such as certified nursing assistant (CNA) or medical assistant (MA) (I work in healthcare so I have experiences in these aspects). I can tell she is very bright, and willingly to learn. However, the issue is her sister (24F) where she refuses to do pretty much anything independently from her younger sister. The older sister has an active driver license but refused to drive/gets distracted very easily (she doesn’t have a car) therefore she relies on my friend to drive her pretty much everywhere, especially to work since they work at same workplace with a same schedule. This causes problems for my friend to do something different with her career since she is the main driver and everything she does need to work for her older sister as well. Her boyfriend also has a job but with different schedule so he can’t help much in that regards.

The last time I talked to my friend, she wanted to do CNA training next year, same with her older sister only because she has someone planned everything for her conveniences. And she isn’t even interested in medicine. She has spending problems with little saved up and contributed unequally to bills and utilities so that leaves my friend and her boyfriend spend way more than they need to. She doesn’t help much around their house. And she claimed it was "depression" that didn't give her the motivation. She lacks critical thinking skills and hates it when her younger sister tells her what to do. She also disrespected her sister by not listening but also being manipulative by bringing up suicide so she can have her little sister do all the work for her.

This is so far what's bothering me the most and I need your advice on how to talk to her older sister about how this is very manipulative and prevent my friend to do what she wants to do with her career. Any advices/questions are appreciated!
