HOW DO I SAVE MYSELF

My sister Janet and her boyfriend Leon want to keep me in a sanitized environment all because Janet got fucked up and no longer likes music and bright colors, when fun fact she wasn't always such a prude, here's a picrew of her when she was cool

she was cool and badass just like me, but then she met Leon, he acted like just her match at the start, but then when she got sick, she was hospitalized, and Leon was there with her throughout her stay, which I find suspicious. By the time she got back from her stay, she looked NOTHING like this, having cut and undyed her hair and dressing "normally", along with her mental instability. around the time she was hospitalized, Leon started getting really freaky, whenever he'd visit, he would steal something and claim it was "for Janet", plus his parents are millionaires which is scary as hell. You think if I save myself I can save Janet too?
