I fuckin hate my sister tbh

She’s 20 and does nothing, she lives with me and our mom still, which is fine but like she doesnt pay bills, or buy groceries, or even do chores. Shes currently in $2000 debt to our mother. I understand she has 2 jobs and all, but like she can still at least do the damn dishes. Or at least try to pay our mother back (our mother covered her bills and her cats needs while she was gone for a few weeks, plus my sister kept borrowing money from her) and whenever our mom tries evicting her my sister says shes gonna off herself. Our mom legit only wants her to start pitching in by either doing some chores or buying groceries and then just paying her back. Its not that fucking hard. She dropped college halfway through the first semester wasting our families money, when she took drivers training our grandparents paid for her segment one but she refused to drive her hours and decided to wait until she was 18 to take her test which wasted their money too. She’s just such a fucking narcissist. She wastes everyones time and money, does nothing for anyone, and literally sucks the fun and life from everything. Not to mention shes the biggest liar ever. She always claims to say she raised me, like no? Our grandparents raised us. You aren't the hero you think you are. All she ever did was hit me as kids and throw temper tantrums. And I know she has bpd, I know it explains her behaviors, but she refuses to take medication for it and refuses to accept the diagnosis. She just wants to take random quizzes online to decide what new mental illness she has. Like she has claimed almost every mental illness you could think of except the one she actually has. She refuses to listen to all her doctors and therapist. Like again, I know shes going through her own shit mentally, but shes not even bothering to get help.
