Is it even possible for my family to get any worse? My parents

Is it even possible for my family to get any worse? My parents are yelling at me 24/7 for the most stupidest things. My parents are always fighting. I feel like they're going to separate....... again. Yes, I said again. Last year my parents separated because they didn't "feel the love" anymore. I was extremely sad and probably cried for 3 hours straight. They separated probably during the spring.  My dad hadn't moved out yet.... weird, and he was living in my basement. He was planning on moving out during the summer. But low and behold when me and my sister went off to camp they decided that they "couldn't possibly love anyone else" so they got back together. Don't get me wrong I'm happy that they're back together, but honestly sometimes I think they are just staying together for my sister's and my sake. Also they don't understand the meaning of PRIVACY.... like seriously it is the most annoying thing ever. And another thing is that when they got back together, they didn't go back to just normally being married, they became gross, mushy, and acted like newly wed, it's nasty. My mom just thinks she can just barge in my room whenever she wants.
