Feeling trapped and helpless

Our family is currently renting/residing in my mother in laws house. She is a manic hoarder. I think I have ocd because the clutter has immobilized me and I need everything clean and organized. This is has caused world war three amongst us since we cannot cohabitate peacefully This house is consuming me and my mental health but I have no other more positive options. We are planning on having a place to move to in a year or so but who knows. Who knows if it will be better? What is this life? It’s horrible. This house is old and decrepit and I have no control over it. I feel like I’m being tortured for being poor.
