I can't do this!

Things have been rough lately. Really rough. I may or may not have mentioned this, but back in December my sister accused my boyfriend of doing something I know he didn't do. I know he didn't because he was with myself and 2 other friends all night the night in question. Yet that is not enough for anyone to be convinced of his innocence. My sister caught off me and my parents (for not cutting me off) and turned the entire family against me. We haven't seen my nephew, but she gets so much fucking support from the family it makes me sick. She mooched off everyone and treated us like shit, then she just walks away and cut us off like we are shit. I struggle with work, school, everything. But the bills pile up and I have no help. For what? Nothing. I try to take it a day at a time, a day at a time, but this nightmare is real, it isn't ending. I just want someone to lean on and there is no one there.
