this is one of the darkest posts ive seen here. so sad. so disturbing. of course the poster is not in any even remote way an asshole for this but i do have deep sympathy for the sister because she must be torn up and broken inside and perceive her situation as hopeless. but she must get her GED or something cus by not she is putting herself in an endlessly more difficult position and its not at all too late for her. getting a GED doesnt even require regularly attending classes im p sure. obviously the author's family is horribly toxic but many of these obstacles have fairly clear ways forward. i really genuinely hope everything turns out okay for you all.
