I feel unmotivated and sad

I am extremely tired of being with my parents. Everything I say is cause for laughter, mockery, fights or maybe "why are you telling me this? I'm your mother/father and I'm always right". I'm already very discouraged with life due to several factors and this is causing me to have some strange thoughts. I know there are people who are worse off than I am, but is a daughter supposed to agree with everything her parents say and bow her head? I don't think it works that way, that must be why we always have fights because I don't bow my head and accept whatever they say or do whatever they want. I feel invisible here, like no one respects me or listens to me. My father is the worst and the one that puts me down the most. He doesn't speak directly to me but speaks to my mother and sister and I always listen to everything he says about me. He always puts me down and talks bad. I avoid talking to him because every time we argue, it's not too big, but it's enough for him to say a lot of things that hurt me including the fact that I'm unemployed. My mom isn't very different either and I feel like my sister is getting a bit like that too. I often wonder if I'm the wrong one, as they are either very freaked out or passive-aggressive. I feel lost, sad and unmotivated.
