So my sister had to stay with me for 2 weeks until her tenancy starts In the past when this has happened I must admit I wasn’t that accommodating or welcoming, however, I would like to think I’ve changed from then. Although I’m not incredibly chatty (we’re not that close) I’m polite and I try to be understanding. My sister is the type of person where if you say no/ ask her to do something it can be difficult. For example, I told her that she should take the keys with her since she was taking a day trip with her friends and that I might be too busy to open the door if she knocked on the- she did not like that. Today, I told her I was going out to pick up some packages. She must have thought I went to get food as she was upset I didn’t return back with snacks. She told me that I had told her I was doing a food shop - I did not tell her this. I apologised either way I then told her I myself wasn’t particularly hungry but she could have the left over takeout from yesterday. This is because I bought a sandwich earlier that day and had done food in ikea ( I needed to buy something there and figured I would treat myself). She proceeds to look through my bag for a receipt and makes me show her my bank statements as proof?? She goes out to buy food - despite me offering to cook/go out and buy something for her. She must have told my mum something like: “(insert my name) told me she was getting food but came back with nothing”. This clearly angered my mum as she told me that I was unfairly treating my sister and accused me of not liking her. Later on today I asked my sister if there was anything I could do to be better. My mum and sister are much closer and I was a lot closer to my brother who unfortunately died. I feel like I’m stuck with people who don’t like me and will antagonise me at any chance I get. I feel like I’m going crazy and would love to know if I’m a horrible person so I can improve 😭😭😭
