Inner peace - living situation issue

Hi everyone I need advice on how I can find some peace within myself. I am so stressed out and frustrated with my living situation. I'm living with my parents and it's been a year now and previously I loved living by myself as I kept my space tidy and looked after all my stuff whereas my parents aren't the tidiest of people and they have a lot of clutter and I cannot stand clutter. Dirty hair brushes, used dishes left in the lounge room. They eat my food. And I know that it's all so small but the small things are just getting to me. And I know I am in there space so should let what is be what is. I'm getting so angry over it all and I need to find my calm and peace. I don't want to meditate. Does anyone know any other options to help get through this year long rough patch?
