A family rant

Im 17 years old. A little back story I️ live with my grandparents and I️ have since seventh grade. I️ used to fight a lot with my grandma every day when I was a freshman and mid sophomore year, I️ grew up and learned to respect her cause she put food in my mouth a bed to sleep on and a roof over my head. She let my uncle stay for a “month” and it turned into a year and a half with his daughter. He has not payed for anything in this house or rent yet my grandma feeds them and lets them live freely I️ never liked him because he used her even before he moved in and is using her even more now. Daily I️ hear him screaming at her telling her to shut up and everytime I️ try to help her she yells at me. She hates me and takes it out on me but won’t kick him out??? So tonight he screamed at her twice and I️ just dont know what to do. I️ seriously am considering moving out because if I️ dont ill hurt this man.. how many other think it’s disgusting for a 38 year old man to be yelling at his mother for doing nothing while she lets him eat live and shower for free and not even try to get a job, he’s been sitting on his ass everyday watching tv instead of getting a normal job. Please comment how you feel so I️ can show my grandma and get her to realize I’m not fucking crazy for hating him !!!!
