My house is dirty and my parents are selfish so how do I deal with a dirty house and selfish parents?

I lived at home all my life with a workaholic father, a housewife mother. My mum always had a cluttered home it got to a point where it was just piled up and I became a hoarder just like my parents. None of my siblings would ever clean the house including me as i was young but heard people say all sorts about my messy home all my life.

It was just us growing up with a selfish father who is stingy. My mother & father showed their true colours once we got into a family argument with my brother & his wife when they let them verbally abuse me in a confrontation and my brother said "no one cares about you" and didn't stand up for me and I felt the betrayal.

My father is so useless it's unbearable & my mother she practically lived as a single mother raising her kids alone.

Anyways we never got pushed towards education as my mum was too lenient and i hated school as she would neglect taking care of me & she only cared about us working but would never give us money for anything beneficial tbh. She was saving money for us but my dad would never spend on us but give to his siblings backhome where he came from.

Anyways the point is I stayed in a toxic environment & I got married recently and my inlaws house is clean and that inspired me to work on my parents home.

Anyways any time something comes about it doesn't stop my parents from leaving me in the dark. I ruined my own life chasing for love all my life with no guidence even that felt like a battle. Anyways my dad loves to people please and abuses me verbally when I stop wanting to live for others , but for myself and my mum just follows him silently and never stands up for me even when I got bullied all my life. Anyways I need to forget priorising my parents how do I do it and how do I forget about my parents who don't take seconds to make me feel unimportant. My sister is the only person in my life who helped me not my parents. I feel ashamed of my dad. I loved my mum but I need to move on from them they are selfish.

My house is dirty and my parents are selfish so how do I deal with a dirty house and selfish parents?
