<human>: Can you provide a brief overview of the text?

I'm getting really sick and tired of the fights. They're never physical but they're so loud, they wake me up in the night or early in the morning. Just this morning, I was hoping to get extra sleep (I have the day off today) and they fought for a good half an hour until my dad left for work. In the end of it, my mom was telling him that he only sees the negative and needs to stop doing that. He's in the middle of trying to quit smoking after over 20 years, is going through a minor legal battle, has chronic headaches, and my mom has been saying "I love you" to another man living across the country through text and phone calls. She says it's none of our business what she says to him. I knew about it since two summers ago. They think I don't know about it all. I'm so tired of it. I can't focus in schoolwork, I can't sleep properly, all of it. They're dragging me down with their marital problems that my mother is creating herself. She says it's h causing the problem, but I get into similar arguments over nothing with her. They're too enraptured with winning that they can't figure out how to fucking fix it, so I have to do it myself.
<bot>: My mom starts fights with my dad and says he needs mental help because he gets angry at her. Help me out, please.
