She’s a pathological liar and her most recent lie she was caught in was “yes I totally turned in that scholarship application” when she didn’t and that caused a big mess. She fails classes out of sheer laziness and still thinks she’s going to survive going to college and being on school sports teams even though she can’t even do that in high school. Yet she always acts like she’s the goddamn victim. Like, I’ll never be able to tell my parents that I’m gay, because I love them too much to break their hearts like that because I think they’re good people and they mean well, even if I think they’re misguided. My sister, however, seems hellbent on ruining them, and she has far less reason to be afraid because all she is is a lazy ingrate. She’s a bitch, and she can just fuck off.
At the end of the day, it’s her life. She’s hurting herself foremost. Sounds to me like she’s struggling to cope with expectations and doesn’t know how else to deal except lie. Meanwhile, you make great efforts to be strong and not tell your own truths. Understandable you’d be angry she doesn’t also suck it up. My siblings have made mistakes big and small (as I have) but compassion and patience can go a long way. I think you may have greater insight into her struggles than you recognize.
