In-laws...

I'm sorry but I need to vent. I am living at my fiance's parents house upstairs on the third floor and we were supposed to have the whole upstairs to ourselves. But his aunt and uncle (siblings not married) are now living in the room next to ours. I have to walk through their room to go downstairs for anything including the bathroom. I am so sick and tired of having roommates and zero privacy. Don't get me wrong I love his family and they're extremely nice and accepting people it's just I get zero privacy and his uncle has been on the phone everyday now basically screaming and I am pretty sure having sex over the phone through facetime or whatever. I cannot deal with this anymore. I like seeing them and spending short times like outings and dinners with them but I cannot take having loud roommates anymore. It's like he doesn't know he's talking like he's screaming. Everytime I open the door to go out of my room he stops talking all together and hides the phone. It's like super obnoxious. I am not used to living like with wayyyy too many people in one house and having them right next door. It's ridiculous. His parents don't have money to have this many people and I give them rent money when I can and help out all the time. But I grew up in a giant rich house with all the privacy in the world and no people bothering me. I have no money but when I get enough to move out we are planning on it. I am just so sick and tired of this. Please don't be mean I know I sound like a rich snob but I am really a nice person but having people around everyday all day because nobody leaves the house because of disability and shit I can't take it anymore. How do you deal with this?? I had my best friend live with me for two weeks at my parents house because she had no electricity in her house or heat and it drove me nuts after like 3 days. Someone help me give me advice anything will do. I am so done. I feel like screaming but it's not my house.
