My little cousin has had intense behavioral problems ever since she was a kid. She was around 16 when she  started seeking help. She's 18 now and she asks me a lot of questions every weekend when I go see her because I am the only other person whom she knows who's getting any help with mental health. I'm borderline and I really think she is too (let's make that a story I'll tell another day). The shitty part is that when she asks me all these questions, I can tell that she's only in that stage where the BPD is not as catastrophic and painful because she attends high school. Let me give you a clearer picture. High school here is just someone putting on uniform, memorizing whatever the teacher is saying, regurgitating it in exams, having school friends but getting along with everyone and having a boyfriend you never have sex with or visit. I had to say that because I've heard that highschool in developed countries is horrible. Ours isn't, it's easy. Leaving that is when things get weird. No structure anymore, no false sense of comradeship that classmates give and now, you have all these effin decisions you're allowed to make. There's no more living at home. Well, you get it right? You're uprooted from the cocoon of comfort plus and this is a big plus, all the things you were trying to avoid doing when living with your parents, you are now free to do. Anyway, my point is it gets way worse when you start having all these questions, all this freedom and all these new friendships. She'll never be half as sheltered as she is now. I don't know how to prepare her for that shitstorm.
