i feel like shit for hoarding and i dont know how to clean/fix my issue and its adding to my mental health struggles

I (21f) live with my mom(48f), aunt(50f), cousin(20m), and my cousin’s gf (19f) and there is already a lot of issues within my family regarding cleaning. My aunt is the homeowner and expects everyone to clean up the entire house for her all the time. As a result my cousin and his gf do nothing all day and play video games and I end up being the one doing 99% of the house cleanup, whilst also managing going to college, job searching, and being the peacekeeper between my mom, aunt, and cousin’s gf and my room has become neglected and is FILTHY. Every time I try to clean it I feel overwhelmed and paralyzed in the mess and it just adds to my already severe depression and anxiety (also have AuDHD). I dont know what to do. Asking for help from my family will most likely end up with me ending up homeless and i cant afford to have a cleaner come in and clean up after me.
