My sister is 1 and a half years older than me, she is 16. lately for the past 2 or 3 years she has been acting all depressed, and i'm sorry if this sounds mean but it's getting a little annoying. Our mom died when i was around 8 and my dad stopped working a little before that, so we never have that much money at any given time. For some reason she thinks that her life is so bad and she has this crazy idea that for some reason she has to care of me, she treats me like a bloody 7 year old, despite the fact that I am only a year and a half younger than her and I am bigger, stronger and more capable than her. for example, the other day, dad went out to a gig (his band is good but they don't earn very much money) and Joanna decided that she was going to go out with her friend and have a 'night out', which basically means that she's going to get drunk and try and hook up with some random guy. So at about 10:00 she comes into the lounge room where i am watching tv and says to me "ok i'm just going out for a bit, are you sure you're going to be ok here alone by yourself" I just look at her and remind her for the hundredth time that i'm bloody 15 years old and that of course i'll be freaking fine by myself. then she just looks at me and says "OK" in a voice that says she thinks that I think I can handle more than I really can, and then says, "well be careful, I'll try not to be too long" and walks out. She continuously acts as though she is one of my parents, and she thinks that she is such a good role model for me (she isn't, alot of the time she acts like a bloody sl#t). nobody asked her to act this way, I certainly haven't given her any indication that I needed another parent figure besides dad, but she acts like it anyway. But the think that's also starting to get on my nerves is the fact that she is always complaining about her life. The other day her friend was over and I could hear her saying to her that "I am so nice to everyone and it's pissing me off that so many people act like b#tches even though their lives are so perfect, if anyone has the right to be a b##ch it's me because my life is so sh#t." Her life is fine, I live in the same F#!#ing house as her, I've had the same traumatic experiences as her, I'm in the same bloody boat as she is, but I am not complaining, I barely ever complain about anything, if anything she's got it better off than me. She has more friends than me, she goes out a lot more often than me and she has more money than me (she has a part time job at a supermarket and wastes the majority of her money, yet she complains about things like when dad doesn't buy alcohol for her and her friends, or she complains at dad for not paying for her to get her ears pierced at the top of her ears after she wastes all her money on going out with friends). And sure, I have those days where I am grumpy and just want everyone to p!ss off, but I assume that just comes with being a teenager and don't have those types of days that often anyway. But she is always acting like she has the worst life in the world, perhaps I am not understanding this correctly or thats just her hormones acting up but it just seems to me like she is being a whiny little b#tch. There are so many people so much worse off than us, I can see that but she obviously can't. whenever I confront her about any of these things she says "you don't understand, I am so depressed OK" so i say that if she thinks that she has depression than why doesn't she go see a psychiatrist, she then replies that "a psychiatrist wouldn't understand". Please help me to understand her if you can, it would be greatly appreciated.
