Pushing my sister to be more confident

I’ve been born into a very conservative family, and I am the first female child born to my parents. This means they were the most strict on me and I grew up with a very rigid set of rules regarding what I am supposed to be doing, how I am supposed to act and how I am supposed to look. They were more lenient on my brother because they are super sexist. It is now after years of fighting with them that I’ve finally obtained the freedom to explore what I like. My sister on the other hand has had to grow up with the wealth of knowledge on how I was punished for doing something differently.<br><br>I’ve been very concerned for my sister for a while, and more so after I got more freedom. She is constantly afraid of making a single mistake, and is incredibly self conscious about stuff. She will never go out of her comfort zone, she will never talk to me about something she is interested in and she will never ever wear anything other than salwar kameez. I am way more open with her, and I’ve been trying to get her to come out of her shell. She is actually very clever and is doing very good in her studies, more than me. She is also very pretty, and I love her a lot, so the fact that she is so afraid of interacting with anybody makes me feel very worried. She has one female friend who is also the only person she talks to, and that is it. She doesn’t even talk to me much, which is more hurtful than anything for me because I used to look forward to having a sister who would be my best friend.<br><br>I’ve been talking to her, giving her more confidence by telling her how pretty and smart she is and all, and she has started to be more comfortable lately, which also made me feel better. However, I am very afraid of what consequences my parents would give her if she does something wrong. I’ve already lined up a plan for us to run away and get help if something like that happens again, and I know that I’d give my life for her, but I really do hope with all my heart she is safe and happy.<br><br>Edit: I am the elder one
