Shes 45, I'm 16, I've finished school a couple of weeks ago and now I'm working every weekday. She works 3 12hour shifts a week. All the time she seems to be angry, earlier tonight we had a big arguement, she asked me to turn my light off because she wanted to sleep. My response was "Ok, in a minute", I was getting my bag ready for work, and she just snapped and started shouting at me. I tell her that I'm getting my bag ready for work I won't be long and she's fine. After my light was off she went into my brothers room, it was a mess, and she started shouting at him. This confused me not only because she wanted to sleep but why bring the fact up when he is supposed to be sleeping as it was about 10.30pm and he has school tomorrow and he's 13. I asked her why she's always angry and she said its because all she ever does is clean and all we (me and my brother) ever do is make a mess. This isn't true I try to help around the house as much as I can as well as working 10 hours a day and I can't seem to do anything right, ever. This morning she asked me to put a t shirt away the minute I was leaving for work, literally just got down the stairs about to go out the door, I said when I got home from work I would. Totally forgot about it, tonight about 10.30 again she says she's asked me loads and I still haven't done it and it's been there all day. I remind her (as politely as I can, I'm getting rather stressed out at this point) that I've been at work and putting one t shirt away isn't particularly a priority when getting in from a long day. She then goes on to say that her ironing my clothes isn't going to be a priority of hers then, comparing ironing my clothes, which she has done for the past almost 17 years, to putting one t shirt away. She always seems angry and it worries me. I want to help her but don't know how, and if I say anything to her about it I always feel bad because I feel like I've patronized her.
